Gas-powered airsoft guns use the pneumatic potential energy stored within compressed gas to drive the shooting mechanism, and thus operate according to an entirely different design principle to spring- or electrically powered airsoft guns. The most common type seen is the gas blowback (GBB) guns.
The ballistics of spring- or electrically powered airsoft guns differ from real firearms in that a longer barrel will not always result in better accuracy. [citation needed] The "sweet spot" for barrel length in a spring/electric powered airsoft gun is around 450 mm (18 in), beyond which added barrel length will not improve accuracy.
Velocity vs. energy chart for 6 mm Airsoft pellets. The pellet speed of spring-powered and automatic electric guns is determined in large part by the tension of the gun's main spring. Muzzle velocity limits are between 90 and 120 m/s (300 and 390 ft/s) for AEGs and 120 to 170 m/s (390–560 ft/s) for single-shot spring sniper rifles. [12]
A para-athlete competing with a match air rifle A collection of lever-action, spring-piston air rifles. An air gun or airgun is a gun that uses energy from compressed air or other gases that are mechanically pressurized and then released to propel and accelerate projectiles, similar to the principle of the primitive blowgun.
Tokyo Marui was the first company to introduce airsoft guns powered solely by electric motor gearbox-driven spring-piston assembly in 1992, which they called "automatic electric gun" (AEG). This compact air pump system was implemented in their first battery-powered automatic firing replica, the FAMAS F1. Other airsoft guns were then introduced.
The hammer itself is a metal piece that forcefully rotates about a pivot point. [2] The term tumbler can refer to a part of the hammer or a part mechanically attached to the pivot-point of the hammer, depending on the particular firearm under discussion (see half-cock). According to one source the term tumbler is synonymous with hammer. [3] [4]
The Supersport, being spring powered, suffers from recoil, range is limited to about 40 m, with 25–30 m being the maximum hunting range and the rifle has a "just under legal limit UK power" of 11.2 ft•lbf (15.18 J) of energy.
Airsoft and paintball guns are a popular toy that operates this way; when used with adequate safety equipment (eye protection at a minimum) these may be used in games involving shooting at other players. BB guns and other low powered air guns are often marketed towards the youth market. However, in many countries they are subject to normal ...
