Airsoft

Airsoft is a term used interchangeably to refer to one or both of the following subjects: A game in which players participate in the simulation of military or law enforcement combat with replica military firearms and military-style tactics A replica firearm scaled either 1:1 (or perhaps as a 'mini' or '3/4'). It may be of metal or plastic, and usually fires 6 mm or 8 mm spherical projectiles weighing 110-600 milligrams (known as "BB"s). Propulsion for the projectile is by manually compressed springs, electric motors, or compressed gas including propane (or green gas, which is propane with added oil), air or HFC134a refrigerant. The game is highly popular in several Asian countries, such as Japan, China (including Hong Kong, Taiwan and Macao), South Korea, and, to a certain extent, Philippines, where real arms are difficult or impossible to obtain due to local laws. For this reason, the vast majority of airsoft guns, accessories, and aftermarket upgrade parts are made in these countries. Despite rumors that Airsoft has been made illegal in mainland China, it is actually legal and very popular, both in mainland China and in Hong Kong and Macao as well. There is currently a growing interest in the West, especially in the United States, Canada, United Kingdom, Germany, Switzerland, France, Spain, Portugal, Finland, Italy, Belgium (where the Dutch players also go, since in the Netherlands it is illegal) and Denmark, bolstered by an active and expanding Internet scene.

It then spread to China, becoming especially popular in Hong Kong, Taiwan, and Macau. It's root can be traced to 1:1 scale plastic model kits of popular real firearms. From that point on it went into three separate directions: air-driven pellet guns, cap-type guns, and pellets driven by a spring. The guns, which had bullets driven by a spring, had a spring in each shell. The bullet was forced into the shell and held by two small locks. Placing the loaded cartridge into the chamber, and firing the gun, would force the cartridge forward and releasing the locks on the bb. The spring would propel the bb forward. Pulling back the slide would cycle the next cartridge. The drawback with this design was that this bullet would have a maximum range of 20 feet (6m). The cap-type guns used a powerful explosive cap to make the noise of the gun and in later versions, to actually eject the spent cartridge from the gun. More sophisticated versions included the MAC-11, and CAR15 with a fully loaded magazine, can fire fully automatic. These guns were good alternate movie-prop guns. But since these guns only cycle the action and make a bang, the popularity of these cap-type guns never really caught on because no projectile was fired from it. Early Japanese air-driven pellet guns had a soft plastic bullet shaped like a pointed mushroom, which was then inserted into a hollow cylindrical plastic shell, which approximated the size of a real gun cartridge and had the look of one. These guns were based from semi-auto pistols, and the plastic cartridges were loaded into a magazine which was then inserted into the gun. The number of cartridges loaded into the magazine would be similar to a real firearm magazine. The gun was spring-powered normally by pushing the slide forward to strip the cartridge off the magazine, loading it into the chamber to fire, and simultaneously cocking back the spring air piston. Pulling the trigger of the gun released the spring piston, the air went through the rear of the hollow cartridge and expelled the plastic pellet through the barrel. By continuing pulling back the trigger, the locking mechanism for the slide would release, the slide moving rearward and the empty plastic shell would be ejected. By repeating this process, another pellet can be fired until the magazine was empty. Unfortunately, this process had some drawbacks. The shells were easy to lose, and the pellets were few and expensive. The next evolutionary design step was to replace the plastic bullet with a round BB. The shell was kept and the BB was inserted into the shell to make a cartridge. A rubber O-ring in the lip of the hollow shell held the BB in place. BBs were plentiful and easier to manufacture compared to the plastic pellet. Eventually, the plastic shell was altogether removed from the design to evolve into the airsoft guns we know of today. The American toy company Mattel had a product in the 1950s called Shootin' Shells, which was identical to the spring-loaded shells described above. A plastic bullet was pushed into a brass spring-loaded shell, and held by two small locks on the bullet. It could be fired from a number of toy guns, including rifles, revolvers, and even a Remington-Derringer hidden in a belt buckle. Mattel also marketed Greenie Stik-M-Caps for use with these toys. These were circular paper caps with adhesive on the back that could be attached to the rear of the Shootin' Shells to make a bang when fired. The caps were only used for noise, not propulsion. Airsoft in American culture began with several abortive attempts in the 1980s by the Daisy BB gun company of the USA to market a BB gun that could be safely shot by opposing players at each other. It was known then as "Replisoft" and "SoftAir," a name which airsoft is now rarely known by. These spring guns used the plastic shell and BB design. The products did not prove popular in the U.S. market. However, the sport continued to prosper in Asia and gained significant popularity. Most modern airsoft technology developments were created in 20 years of expanding interest in Japan. Growth in the West Starting with early 2003, Daisy has once again begun marketing airsoft guns for sale in the United States, under their "Powerstrike" brand name. This and other models have begun appearing en mass in major brick and mortar distributors, expanding what in the US was traditionally a generally Internet based operation. US-based manufacturers of tactical gear and equipment have also begun to recognize the game, some marketing products specifically for use in airsoft. On the Internet, the online auction site eBay has noticed airsoft as well, and has created several categories specifically for the thousands of listings of airsoft gear and guns. Airsoft also serves to familiarize a younger generation with firearms and their proper handling in an age where firearms have a certain stigma attached to them. Methods and Structures of Play Several common game modes are as follows: Deathmatch / Free For All In this mode, all players are set against each other; there are no teams and alliances between players are usually frowned upon. This mode is usually the most frantic because players have only themselves to rely on, meaning dealing with fire from numerous directions and more difficulty gaining solid cover. Examples: Last man standing (Ultimos homo statans) Team Deathmatch / Teams In this mode, teams are formed between several players. Usually the teams are balanced (no team has more players than the other). The members of a given team have to work together to eliminate all the other players in the game. When all of the players on a team are out, that team is eliminated. This continues until all teams are eliminated. A variation on this is seek and destroy, where one team hides and the other team must find them. Examples: Last team standing Capture the Flag The classic kid's game with a twist: (usually) two "bases" are set up with a flag (or similar objective) in each one. The players are divided into teams and have to steal the flag from the other team's base and return it to their own. Usually, if a player is "killed," they can return to their base and start again. Examples: Traitors (each team has one player that is a traitor) Center Flag Similar to capture the flag but only one flag that is placed in the middle of the two teams bases. First goal: capture the Flag. Second goal: take the flag to enemy base. When the flag reaches the enemy base, the enemy loses. If the flag carrier is eliminated anyone can pick up the flag. For extra long games, multiple flags can be used. Examples: Capture explosives (1st goal) + Commando raid (2nd goal) Siege or King of the hill In this game type, there are two teams: Attackers and Defenders. The Defender team is given a usually fortified position while the Attacking team has to kill all of the Defenders in order to win. Examples: hostage rescue (SWAT team) Carry the flag One flag and one team carrying it. Objective is to take the flag from point A (normally team base) to point B. The interception team objective is to prevent the flag from reaching point B. There are two variants of this game type, one for long games and another for short games. Games can be longer if anyone can be flag carrier or shorter if only one flag carrier exists. The game ends when no more players to carry flag (long version) or when flag carrier is killed (short version). Examples: president rescue/walk (single flag carrier), Drag the doll (multiple flag carriers), Arm&Destroy objective/Bombing run/place the bomb (flag/bomb carrier). Grab the flag One flag is placed in a location away from all teams. The objective is to be the first to reach the flag. The player/team that first reaches (grabs) the flag alive wins. Examples: Manhunt (one player tries to reach flag - escape), prisoners escape (multiple players trying to reach flag - escape) MilSim This is airsoft combined with live action role-playing elements, where multiple missions have to be carried out by all teams of players while the mission objectives of each team are very likely to interfere with each other. This type of game often takes whole weekend of play time, where the gameplay maintained during nighttime, so even more strategic elements like setting up observation posts and the like become key. Not all players have such structure in their games and are simply there to have fun, not to compete. This is obviously not a complete list; many more game modes may be invented every time a few friends get together to play. Games listed above may or may not be mil-sim and other serious airsofters play historical reenactment that replicate a combat zone or historical event where players wear camo and play scenario based games with squads, objectives and realistic missions. Airsoft guns Airsoft guns are classified as "toys." There are rumors that these "toys" can be modified to kill; however, airsoft enthusiasts know this is far from the truth. There are also rumors that the Japanese Yakuza (Mafia) converted airsoft guns to fire real pistol cartridges, but are limited to a single shot. It is impossible to convert any airsoft replica to fire a real bullet due to its materials, internal design, and construction. Most rumors are driven by the realistic look of the airsoft gun and ignorance about the internals beneath the gun's "skin", a simple mechanism that cannot seriously injure people. Also, airsoft barrels are too thin to use a real bullet. If someone was to replace all of the parts necessary to use a real bullet, they would have been simply built a real gun from scratch. The guns used in airsoft are typically replicas of real firearms. Airsoft guns can be divided into three groups by what powers them: spring powered, electric powered, and gas-powered. Spring powered Spring-powered airsoft guns (often called "springers" or "spring guns") are single-shot devices that use potential energy stored in a spring to launch an airsoft pellet down the barrel of the gun. The user must cock a spring gun prior to each shot much as you would a real shotgun or bolt-action rifle. This is typically achieved by pulling back the slide (pistols) or bolt (rifles), which in turn compresses the spring and makes the gun ready to fire. Because of this, these guns are incapable of automatic or semi-automatic fire. While most electric guns also use springs for this they are not considered to be in the same category as the single-shot spring-powered guns. Low-end spring guns tend to be much cheaper than their electric-powered equivalents due to their simplicity and cost of components (spring assembly, electric motor, battery, and battery charger) and thus are widely available. These guns are less suited for competition because they are at a disadvantage against automatic guns in close combat and do not provide enough accuracy and power for long-range uses. Higher-end spring-powered airsoft rifles can be quite expensive; these guns are typically suited for "marksman" applications in airsoft matches and can provide competitive muzzle velocities Gas powered An example of a Gas Blowback pistol. Gas-powered airsoft guns use pressurized gas to propel pellets. These guns are capable of automatic and semi-automatic operation. The most common gases used are propane (usually referred to as "green gas" by airsoft players) and HFC134a refrigerant. Less commonly used gases include CO2 and nitrogen. Gas power tends to be used in airsoft pistols where size constraints make electric-powered mechanisms impractical. Other instances where gas is favored are where adjustable velocities are required or where a blowback feature is desired. A blowback feature is a mechanism which cycles a slide or bolt to better simulate a real firearm's operation. Because of the mechanical complexities involved with distributing and regulating gas, these guns have largely given way to electric guns for less specialized applications. Electric powered Tokyo Marui MP5-SD5 AEG Electric-powered airsoft guns typically use a bank of rechargeable batteries to drive an electric motor, which cycles an internal piston/spring assembly in order to launch pellets. Automatic and semi-automatic operation is possible which gives these guns the popular name "automatic electric guns" or AEGs. These guns often attain muzzle velocities of 200 to 400 feet per second (60 to 120 m/s)(fps measure by a chronograph) and fire rates of 300 to 900 rounds per minute and are by far the most common and widely available airsoft guns in serious competition use today. These guns were originally developed in Japan, and the Japanese model giant Tokyo Marui dominates the market today with many quality models. In a Marui AEG, the motor drives a series of 3 gears mounted inside a gearbox. The gears then compress a piston assembly against a spring. Once the piston is released, the spring drives it forward through the cylinder to push a pellet into the chamber, through the barrel, and forward from the muzzle. Many manufacturers have now more or less replicated this basic model, adding reinforced parts or minor improvements. These weapons are powered primarily by two types of rechargable battery packs. These are Nickel Cadmium (NiCad) or Nickel Metal-Hydride (NiMh) and come in ranging voltages and mill-Ampere hours. The most common battery combination is 8.4v 600mAh, which is a small type battery, in comparison to other available mAhs. Other options include 7.2v and 9.6v ranging from 600mAh to over 3000mAh. The rule of thumb usually is the higher the mAh, the higher rate of fire (RoF) and longer the battery lasts. External modifications, such as metal bodies and reinforced plastics that make AEGs look and feel even more realistic, have become very popular. AEG manufacturers such as Classic Army (Yick Fung) and ICS (I Chih Shivan) produce replicas that are nearly identical to their real counterparts. Most AEGs produced as of late are designed to be as realistic as possible. The two most common AEG fielded by players everywhere are the armalite series (AR-15, M-16, M-4, M-733 for example) and the AK or Kalashnikov series (AK-74, AK-47 etc.) as parts for repairs or modifications/customization options for these two types of AEGs are commonly available. The third most common AEG is the Heckler & Koch MP5 series for the same reason. AEP New to the world of Airsoft is the AEP - for Automatic Electric Pistol, first introduced by Tokyo Marui with their Glock-18C. The AEP is the first handgun to incorporate an electric powered system, capable of full-automatic operation. Because the AEP technology is relatively new, the velocity of the pellets is considered slow for airsoft play. The velocity of the AEP is usually between 200 to 225 feet per second. LPEG's Becoming increasingly popular as an alternative to the Japanese Tokyo Marui guns are the Chinese airsoft guns, made by manufacturers such as CYMA and WELL. Though technically these guns are AEGs by definition, the are often referred to as "LPEGs," or "Low Price/Power Electric Guns". This distinction is made because of the large gap in quality and performance when compared with "true" AEGs. While these are much less expensive than the high-end Tokyo Marui guns and come with all sorts of bells and whistles (laser sights, silencers, etc.) they are of much lower quality and are not well suited for competitive use like their Japanese counterparts. They are often an attractive option for newcomers who are looking for a fully automatic rifle but do not want to pay the high prices for the top quality models. Since spring action guns that can notably outperform LPEGs can be found at comparable prices, it is generally accepted that the spring guns are a better choice. Remember not to confuse this guns with Mini Electrics, as described below. Mini Electrics Recently, the company UHC, well known for its AEGs and top of the line spring guns, began manufacturing a very nice range of Electric guns firing only full auto in miniature size. They are often called "pee-wees" by experienced airsofters, but they average about 120 feet per second and fire quite well. Although they at first look would be belevied to be like the low end Chinese made Airsoft guns, they actually are nice weapons. They are both made in realistic versions and clear versions that are great for playing small games inside or in a neighborhood were a real looking gun is unnaceptable. Also, although they are cursed with a small ammo capapcity (a very fast going 50 or so shots) they have good range, a working hopup, and are fun to shoot. Even among long experienced airsofters, they are great for impromptu games and for kids. They have become very popular in recent years, and are now being imitated by the Chinese company HFC, which are still guns, but not very sturdy. (TS Allen) Components The various internal components of airsoft guns can usually be replaced or upgraded. The following is a short list of commonly referred to parts. Not all of these parts apply to all airsoft types (spring and gas-powered guns don't use batteries, for example). Barrel - Serves the same purpose as in real firearms: guides the pellet and maintains the stream of pressure behind it. Battery - Powers the motor that moves the spring assembly. These are typically NiCad rechargeable batteries but may also be NiMH. Gearbox - Typically a metal housing that contains a gear assembly that transfers the electric motor's drive to the air piston assembly. Sometimes referred to as "Mechbox" Hop-up - A small rubber or metal bucking that applies a backspin to the pellets to improve range and accuracy. The level of hop-up is adjustable on many models of airsoft guns. Electric motor - Used to provide energy to cock the springs in AEG's. Nozzle - A plastic or metal piece that connects the hop-up assembly to the air piston. Spring - Spring and electric guns both use springs to propel the pellets. The stronger the spring, the more powerful a gun will be, but rate of fire will decrease with the spring's stiffness increasing. Valve - high-flow valves are often added to gas guns to increase power (although on blow back guns these usually need to be coupled with a metal slide upgrade, as the high-flow valve increases blow back power as well as bb velocity and will break a plastic slide) BB Guns This pneumatic gun is usually powered by a compressed gas, an electric revolution, or a spring. Most BB guns are shaped like normal guns but can look like toys. Some have reservoirs to store ammunition, some are breechloaders, and others are muzzleloaders. The name of the gun is due to the original ammunition it used, which came from the lead shot used in a shotgun shell. "BB" (0.18 inch) was the size between "B" and "BBB"; modern rounds are made of non-toxic steel, plastic or copper, and are usually .177 caliber (4.5 mm). Some also use shaped pieces of lead called pellets. These vary widely in shape, but generally have a flared back end for stability in flight and either a sharp point or blunt tip. Two well-known American manufacturers of BB guns are Crosman Corporation and Daisy Outdoor Products. Airsoft pellets Some 6mm plastic airsoft pellets Airsoft pellets (often referred to as "BBs", short for "ball bearing" or "big ball" in reference to smaller shotgun shot) are typically made of plastic and are almost always 6mm spheres. Pellets of a given size come in different weights ranging from 0.12 to 0.43 g. In addition to standard plastic pellets, starch-based biodegradable, metal coated, graphite coated (often used by snipers), and steel pellets are also available. Pellets other than 6 mm, 0.12 g, 0.20 g, or 0.25 g plastic or biodegradable pellets are not commonly used outside of Japan. For 0.43 g BB's, you will need a powerful airsoft gun, or get upgrades on your gun so that it can effectively shoot this heavy BB. Glow-in-the-dark tracer pellets are also used in conjunction with a special device that "charges" the pellets up by flashing it with a quick burst of UV light prior to firing so that they remain luminescent in flight for use during nocturnal operations/games. Tracer BBs have been made and leave a white streak behind the BBs path while it's airborne to see where your BBs are hitting for better accuracy. There have also been guns made that shoot aspherical pellets. The best known of these is the Asahi "Blade Bullet", which are now extremely difficult to find and quite expensive to buy. These were designed to be shot from the short-lived Asahi M700 and M40 premium grade rifles, which were produced in 1993. Compatibility with other airsoft guns is highly limited, especially due to their inability to be used with hop-up features. Paint pellets are available but are incompatible with guns with hop-up features as the hop-up will break the pellet in the gun. Paint is very unpopular with airsofters because it tends to stain gear and clothes. 6 mm pellet weights and their usage 0.12 g - Used by some gas and spring weapons. High velocity and low stability. Not to be used in high end AEGs such as Tokyo Marui and Classic Army 0.15 g - Same uses as 0.12 g. Uncommon. Not to be used in high end AEGs such as Tokyo Marui and Classic Army 0.20 g - Standard weight for most weapons. AEGs uses these or slightly heavier pellets. 0.23 g - Heavier pellets for AEGs. Blends speed of 0.20g with range and accuracy of 0.25g. 0.25 g - Heaviest weight for standard AEGs, blowback and spring guns. For an AEG, you will usually need an upgrade to effectively fire 0.25 BB's. Tokyo Marui standard pellets for AEGs, they usually send 200 of these with one of their AEGs. 0.30 g - Standard weight for most sniper rifles. Western Arms pellets for their gas blowback pistol series. Uncommon. 0.36 g - Heavier pellets for sniper rifles. Very slow but high stability. 0.43 g - For the highest level of upgrades in spring and gas sniper rifles. Graphite coated. 8 mm pellet weights and their usage 0.34 g - Low weight for 8mm sniper rifles. 0.45 g - Standard weight for 8m sniper rifles. 0.60 g - Heaviest weight for 8m sniper rifles. NOTE: All BB weights are in grams (g) Pellet ballistics Pellet velocity, energy and weight The pellet velocity of automatic electric guns is determined in large part by the tension of their main spring and so there tends to be a stratification of values. The most common airsoft velocity limits are between 300 to 400 fps for AEGs and 400 to 500 fps for single shot guns (sniper rifles). Here are some common levels of airsoft gun pellet velocity. Unit equivalents Pellet velocity 76 84 85 91 100 107 115 122 137 152 168 (m/s) 250 275 280 300 328 350 377 400 450 500 550 (ft/s) Weight 6 mm pellets 0,12 g 0,35 0,42 0,44 0,50 0,60 0,68 0,79 0,89 1,13 1,39 1,69 0,15 g 0,44 0,53 0,55 0,63 0,75 0,85 0,99 1,11 1,41 1,74 2,11 0,20 g 0,58 0,70 0,73 0,84 1,00 1,14 1,32 1,49 1,88 2,32 2,81 6 mm Crony 0,23 g 0,67 0,81 0,84 0,96 1,15 1,31 1,52 1,71 2,16 2,67 3,23 0,25 g 0,73 0,88 0,91 1,05 1,25 1,42 1,65 1,86 2,35 2,90 3,51 0,30 g 0,87 1,05 1,09 1,25 1,50 1,71 1,98 2,23 2,82 3,48 4,22 Energy 0,36 g 1,05 1,26 1,31 1,51 1,80 2,05 2,38 2,68 3,39 4,18 5,06 (J) 0,43 g 1,25 1,51 1,57 1,80 2,15 2,45 2,84 3,20 4,04 4,99 6,04 8 mm pellets 0,34 g 0,99 1,19 1,24 1,42 1,70 1,93 2,24 2,53 3,20 3,95 4,78 0,45 g 1,31 1,58 1,64 1,88 2,25 2,56 2,97 3,34 4,23 5,23 6,32 8 mm Crony 0,60 g 1,74 2,11 2,19 2,51 3,00 3,41 3,96 4,46 5,64 6,97 8,43 Paintball pellets 3,00 g 8,71 10,54 10,93 12,54 14,99 notes: Velocity vs energy chart for 0,20 g and 0,45 g Airsoft pellets. 3.00 g is the typical weight for a paintball pellet.

Higher energy but different collisions read Elastic collisions (airsoft) and Inelastic collision (paintball) topics for further information. Red lines are the usual Crony (cronograph) weights for 6mm - 0,20 g and 8mm - 0,45 g. Dangers to humans Airsoft pellets typically leave small welts on human targets. While mildly painful, pellets aren't especially damaging to the skin. Eye protection is universally required to prevent damage to eyes. It is also often recommended that full face masks be used during airsoft matches to protect the players' teeth and ears as on very rare occasions players have had teeth chipped or knocked out or ears injured by a well-placed pellet. The pellets can easily punch through a soda-can. The following excerpts are from the United Kingdom Parliament's "Principles of firearms control", Home Affairs Select Committee Second Report, 6th April 2000, expound on the level of danger involved with low-energy projectiles: "25. The Firearms Act 1968 defines a firearm "a lethal barrelled weapon of any description from which any shot, bullet or other :missile can be discharged".[51] In this context, a "lethal weapon" means a weapon capable of firing a projectile with sufficient :force to inflict more than a trivial injury, i.e. with a force sufficient to puncture the skin.[52] The force with which a firearm :is able to deliver a projectile is normally expressed in terms of the kinetic energy it generates at its muzzle—the "muzzle energy". :This energy is normally expressed in units of foot-pounds (ft·lbf) or joules (J).[53] <p> "26. The Home Office and the Forensic Science Service considers that the lowest level of muzzle energy capable of inflicting a penetrating wound is one foot pound force (1.35 J): below these power levels, weapons are "incapable of penetrating even vulnerable parts of the body, such as the eye".[54] However, more recent analysis by the Forensic Science Agency for Northern Ireland has indicated that a more reasonable assessment of the minimum muzzle energy required to inflict a penetrating wound lies between 2.2 and 3.0 ft·lbf (3 to 4 J).[55] We will deal more fully with this discrepancy at paragraphs 123 to 130 below." <p> "123. The power level at and above which an air weapon is considered a firearm in law is presently set at 1 ft·lbf. However, we note above that the Forensic Science Agency of Northern Ireland has more recently assessed the power level at which a barrelled weapon is capable of inflicting a lethal wound as between 2.2 and 3 ft·lbf, and the Secretary of State for Northern Ireland has proposed that the law relating to firearms in Northern Ireland be amended to take this into account.[201]" </blockquote> Based on the Firearms Act 1968, the 3 J limit is indicated by Forensic Science Agency for Northern Ireland as the lower limit to inflict a lethal(paragraph 123)/penetrating(paragraph 26) wound. On another document also regarding firearms, "The Eleventh Annual Report of the Firearms Consultative Committee", the penetration levels lies between 2 and 3 J based on a research for US Army and DiMaio's work in "Minimal Velocities Necessary for Perforation of Skin by Air Pellets and Bullets, Journal of Forensic Sciences". Performance Airsoft guns shoot 0.2 g BBs at velocities from 100 ft/s (30 m/s) for a low-end spring pistol, to 550 ft/s (170 m/s) and beyond for heavily-upgraded customized sniper rifles. Most non-upgraded AEG's using the Tokyo Marui system are in the middle, producing velocities from 270 to 300 ft/s (80 to 90 m/s), but upgrades to the internal components can increase the pellet velocity significantly. Internal modifications revolve around increasing the rate of fire and the velocity of the pellets. The rate of fire is increased by using a battery with a voltage of 9.6 volts or higher. In Tokyo Marui AEGs, the stock gears would have to be replaced with stonger gears since the higher rate of fire could strip the OEM types. The velocity of the pellets is increased by installing a stronger spring. As with any modification, an upgrade on one internal part means the other internal components might have to be upgraded as well. Airsoft guns commonly come with mounts on which you can add external accessories. Some common upgrades added are flashlights, scopes, laserpointers etc. Since airsoft guns have the exact external frame as real guns you can use these external upgrades meant for real guns. Airsoft gun care Barrels should be cleaned after every extended use especially in sandy environments. After playing airsoft, you should fire two to three shots in semi-automatic mode to decompress the gearbox spring. Empty the magazine in order to preserve the strength of the magazine spring. For guns with Hop-Up, you should turn off your Hop-Up if you are not planning to use your gun within two to three days so that it will not expand your O-Ring to make the Hop-Up not work as well and eventually snap. Hop-up & Bernoulli's principle Bernoulli's principle as applied to an airsoft pellet is as follows. As a spinless spherical pellet flies along its trajectory through the air (the air being the "fluid" in this case) the pressures on all sides of the pellet are equal because the air is traveling the same velocity relative to the surface of the pellet. If a spin is applied to the pellet about an axis perpendicular to the velocity vector (e.g, a backspin) the air will be rushing faster (relative to the pellet surface) on the side that is spinning away from the velocity vector and slower on the side that is spinning towards the velocity vector. Bernoulli's principle says this difference in fluid velocity implies a difference in pressures, which is a force that will cause the pellet to move in a direction perpendicular to the velocity vector. Airsoft hop-up devices apply a backspin to the pellet so that the pressure force acts on the pellet opposite to the direction that gravity is pulling it. This causes the pellet to fall less over a given distance than it would without the spin applied to it. In airsoft guns this is often implemented as a rubber piece at the rear of the barrel that is thicker at the top of the barrel than the bottom. As the pellet moves past this piece it tends to roll, inducing a backspin. This is usually adjustable so that the effect can be tuned. Airsoft vs paintball Most people do not realize that airsoft has been around much longer than paintball. Paintball first came on to the scene in the United States in the mid-1980s through the use of utilty companies' paint marking guns, which mark power/utility poles. Airsofters (those who play the game) normally argue with paintballers. Paintball has gained greater popularity and more quickly than airsoft in the U.S. However, in Asia airsoft is much more popular and paintball is nearly non-existent. It should be noted that while airsofters and paintballers are serious about their sport, the debate between them is often not. Both sports offer upsides and downsides. Airsoft rounds are a lesser threat to players, they do not leave as much bruising as paintball rounds, and are less painful than paintball rounds. Paintball rounds contain more mass and therefore carry more kinetic energy than airsoft rounds. Airsoft rounds, on the other hand, are smaller and hence have less kinetic energy, but are also affected by the wind considerably and have shorter range. Airsoft BBs are much less expensive than paintballs. Airsoft can also be played in indoor areas that are more confined because the only thing needed to clean up after an airsoft match is a good vacuum cleaner. Generally, airsoft is inherently much cleaner than paintball. Airsoft is somewhat easier to introduce new players to. This is because at an airsoft playing field, players who use rental guns are not at as much of a disadvantage as paintball players who use rental guns. This is because AEGs are generally manufactured to the same specifications. Style of play also greatly differs between airsoft and paintball. Airsoft players wear camouflage and military gear to more closely replicate a soldier of a certain period while many paintballers wear brightly colored extreme sport clothing, many times replica jerseys of high level paintball teams. Many paintball games are played as speedball games on designated paintball fields. Airsoft is often scenario based and played in large areas of wooded land. However, this is not the rule. Many airsoft games are played on paintball fields and many Paintball games are scenario based. Many people ask how players know they are hitting their target. Unlike paintball, which would leave paint on impact, airsofters can take a shot to the chest and, with enough layers of clothing, may not even feel the hit. The honor system is used, and surprisingly works, as long as the player is aware they are hit. Oddly, the low popularity of the sport allows for the effectiveness of the honor system. Those that gather to play in skirmishes normally know each other, making the games more fun and relaxed. The ever-rising popularity of the sport - no doubt to be accompanied by heightened competitiveness - will test the continuing effectiveness of the honor system. When the honor system fails, there is still one solution. Keep shooting the other player until you hit them in the right spot. In some Airsoft matches (especially those with an un-even number of players), there can be one or more impartial "Judges" or "Referees" who can watch players to make sure they follow the rules. This 'honor system' is one of the issues that prevents any sort of serious league play like paintball has. Many airsoft teams and organizations have strict rules dealing with allegations of cheating. Unfortunately it can be impossible to determine exactly what happened unless the event was witnessed by a third party. However, at this point in time, airsoft is following closely behind paintball's footsteps. Many more people decide to play paintball as it is much more popular in the United States and has its own benefits when compared to airsoft. Legal issues Airsoft guns and playing airsoft is legal in many parts of the world, but not all. Some countries have specific restrictions such as maximum muzzle energy, rules against using the trademarks of real firearms, and special marking requirements (such as brightly colored barrel tips). In Australia airsoft is illegal for most practical purposes. Australian law classes the replica weapons as firearms, and acquiring a licence to possess (e.g.) a pistol requires a rigorous and laborious process of police background checks and fingerprinting. Anyone found in Australia possessing an unlicensed airsoft pistol faces the same charge as a person who unlawfully possesses an actual firearm. In the United States, some Federal Firearms License holders (gun shops) are expanding their business into airsoft. This is because airsoft guns often sell much faster than their firearm counterparts. There are also not as many restrictions on selling airsoft such as the required criminal background check along the required 4473 form and the restrictions on sales to people who live out-of-state which slows down business. The following regulations apply: New York City has a total ban on airsoft guns. Michigan restricts the purchase of these guns so that they may only be purchased from a licensed retailer. Under Federal Law, Airsoft guns are not classified as firearms. Orange tips must be present on the barrel ends of the airsoft gun when they are shipped in a manner that crosses state lines. Once you own the airsoft gun, you may not remove the orange tip, however, many people do. Airsoft guns' trademarks and factory markings must be removed where the Airsoft Gun Manufacturer does not have an existing License Agreement with the "Real Steel" gun's Manufacturer in the US. (Example: Tokyo Marui does not have a licensing agreement with Colt - the trademarks must be removed from Tokyo Marui's M-16 replicas prior to importation. Classic Army has a licensing agreement with Arsenal Arms, so the trademarks can stay on imported replicas of Arsenal's SLR 105 A1. In practice enforcement is hit or miss. You might get an "unlicensed" gun through customs with Trademarks intact, while a Licensed gun might be held in Customs by an "underinformed" customs agent.) In addition, the similarity between genuine firearms and airsoft replicas is close enough to provoke interaction with law enforcement personnel if an airsoft gun is mistaken for its real counterpart. If someone were to, for example, attempt a robbery with an airsoft gun, they would be charged as if the airsoft gun were a real firearm. In Austria following regulations apply: Airsoft guns and pistols are allowed up to 0.08 joules. All users that are at least 14 years old, do not need their parents permission. Airsoft guns and pistols more than 0.08 joules can be purchased in specialised weapon shops only and all users have to be at least 18 years old In Belgium following regulations apply: Airsoft guns and pistols can only be bought at officialy licensed dealers, who carry a government permit to import and sell firearms. In Canada following regulations apply: Low powered airsoft are considered replicas because they do not cause any bodily harm. Airsoft that fire above 500fps AND 5.7 joules are considered firearms and must be registered. Since many airsoft would be prohibited if they were real firearms the owner would need the appropriate (and almost impossible to get) licenses. The importation and sale of airsoft is restricted and must be done by a movie props company. Airsoft used to commit a crime is treated as if you had the real gun, assault weapons carry an extra mandatory sentance in addition to the regular punishment for the crime commited. Ontario the minimum age to purchase airsoft is 18. In the Czech Republic following regulations apply: Trade with them is regulated under the weapon law and all airsoft guns must be authorized by the Czech Gun and Ammunition Testing House before usage. Airsoft guns have the same status as real weapons. The use of Airsoft guns is allowed for players that are least 18 years old. If children of at least 15 years want to play, an adult must supervise the game. Air Soft Guns may not have an energy greater than 16 joules. The use of laser sights is forbidden Usage and open carrying of air soft guns in public places. In Denmark airsoft guns are mentioned in the Danish "Våbenlov" (Arms control legislation). You have to be at least 18 years old to buy, hand over, possess and use Air Soft Guns. A firearms certificate is not required. In Germany following regulations apply: Airsoft guns under 0.5 joules can be freely sold to and used by persons of at least 14 years of age. All Airsoft guns above 0.5 joules must be semiautomatic only and can only be sold to people 18 years or older. Sales of guns of more than 0.5 joules are allowed only in weapon shops. Guns must be marked with the trader's weapon abbreviation and a F-pentagon as well as the airsoft Gun caliber such as 6mm. Laser sights as well as flashlights are not allowed. In Luxembourg all Air Soft Guns are treated under the national weapon law and demand a personal user certificate. In The Netherlands the law places full restrictions on Airsoft Weapons, rendering the possesion illegal. Even when issued a permit to own firearms, airsoft weapons are still illegal, with no excemption possible. Dutch Airsoft players therefor frequently visit Belgium, where they also store their guns. The Norwegian Arms control legislation (Våpenforskrift) requires: One to be at least 18 years old to buy, hand over, possess and use Air Soft Guns A firearms certificate is not required. In Slovenia following regulations apply: One has to be at least 18 years to buy airsoft guns. If the velocity of an airsoft gun is below 100 m/s (328 ft/s) i.e. equivalent to 1 joule, it is considered to be a toy. If the velocity is higher than 100 m/s (328 ft/s), the Air Soft Gun is classified as a section D weapon in the Firearms control legislation of Slovenia. Additionaly Air Soft Clubs and National Shooters Association in Slovenia recommend that Air Soft Gun velocities should not be above 100 m/s (1 J). Airsoft Guns are regarded as low power weapons in Spain and AEGs must have: Semiautomatic rifles and pistols: less than 24.4 joules Other automatic electric guns: less than 1.00 joules and local police validation. In Sweden, one must be at least 18 years old to buy Air Soft Guns. Players in Sweden are often very protective about this, and does not like players under 18. In Switzerland following regulations apply: Airsoft guns are not considered as subject to the weapon legislation and no permission is necessary. Please note that all kind of laser sights are forbidden. In Japan following regulations apply: Legal requirements are set on airsoft model manufacturers to prevent any possibility of a replica weapon being converted into an actual firearm. Standards include (but are not limited to) use of low-melting point metals and non-ballistic plastics in structural components and incompatability of mechanical components with actual firearm components and mechanisms. The overall litmus test used by the Japanese National Police Authority is whether the replica weapon can be made to chamber and fire an actual round of ammunition. These standards have proven successful within Japan, as it has been found that criminal elements discovered that it is significantly easier to purchase an actual illegal weapon in comparison to modifying a comparitively fragile replica into a functional firearm. Due to this reality, most crimes involving a threat of physical violence are often perpetrated with edged weapons, as firearms seen in public are (by default) believed to be toys by the public at large. In the United Kingdom there are currently certain restrictions on the possession of airsoft replicas, which came in with the introduction of the ASBA (Anti-Social Behaviour Act) Amendments, which prohibit the possession of any firearms replica in a public place without good cause. The prohibition of self contained gas cartridge weapons similar to that made by Brocock can arguably apply to Moscarts and BB-Shower grenade systems, however a formal case precident has yet to be set. The Violent Crime Reduction Bill, now under debate, may prohibit the sale, manufacture and import of any replica weapon, including those used for Airsoft. This would mean the eventual end of the sport in the UK, as guns break and could not be legally replaced. The Airsoft community in the UK and other countries have started a public campaign in order to try and save Airsoft there. Due to the VCR bill, British Airsoft players, retailers and sites have had to look to the future by forming associations, the first and prior to VCR was UK Airsoft Sites Governing Body UKASGB, followed by the retailers UK Airsoft Retailers Asociation UKARA, with the first official players body for the South West region UKSAPA, latest to be formed is the Association of British Airsoft ABA which is currently along with UKASGB in talks with the Government with regards to gaining an exemption for the sport. The ABA are asking people to show their support by filling in a Supporters Form [1] and those people who are a part of the sport to register at the site in case membership is required by the government in the future to enable Airsofters to take part in their sport. Major Airsoft Companies There is a great divide between airsoft companies. The majority of quality manufacturers can be found on the internet, but have little to no street prescence, except at specialty shops. However, in some states such as Tennessee, small street airsoft stores can be found. These stores usually carry Chinese-brand airsoft guns, which are all plastic. However, one company, UTG, is turning around the China stereotype with high end Chinese-made guns. High quality companies manufacture mostly AEGs and Gas Blowbacks, and include: Tokyo Marui ICS(I Chih Shivan) G&G (Guay Guay Gunshop) Western Arms Tanaka, which specializes in revolvers Classic Army TOP Star Systema, which specializes in training weapons G&P UTG KSC/KWA Maruzen Marushin HFC(Ho Feng Company) Lower end companies, which mainly produce springers, include: UHC CYMA(Well) SoftAir USA CSI Neonfire Some of these companies' placements may be disputable, but are based on overall quality of all their products.
