Spring-powered airsoft guns (or "air-cocking guns" as called by Tokyo Marui) are single-shot devices that use the elastic potential energy stored within a compressed coil spring to drive a piston air pump, which is released upon trigger-pull and rapidly pressurizes the air within the pump cylinder to in turn "blow" pellets down the gun barrel.
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]
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.
.22 caliber barrel liner, spring, fasteners .22 LR: A mostly printed .22 LR pistol. Uses a DIY metal barrel, firing pin, and spring. Simple and extremely cheap, designed to cost $5-$8. Commonly created to be sold at gun buybacks for profit. [34] A large number of remixes and variants of this design have been created. The Urutau [35] [36] [37 ...
Airsoft is a sport in which players use airsoft guns to fire plastic projectiles at other players in order to eliminate them. Due to the often-realistic appearance of airsoft guns and their ability to fire projectiles at relatively high speeds, laws have been put in place in many countries to regulate both the sport of airsoft and the guns themselves.
Hop-up [1] is the backspin put on airsoft pellets and BBs to increase their range via the Magnus effect. Hop-up devices apply backspin to the projectile reducing the air pressure on its top side. This causes the plastic pellet to fall less over a given distance than it would without the spin applied, extending the effective range of the weapon ...
Mainsprings can come in many shapes, such as a cylindrical spring (Mosin-Nagant, TT-33, Colt M1911), plate spring (Nagant revolver model 1895, Makarov pistol) or spiral spring (Kalashnikov). On a number of automatic firearms, the recoil spring may also function as a mainspring ( FN Browning M1900 , Degtyaryov machine gun , and some submachine ...
A new breed of automatic firearms that combines the light weight and size of the submachine gun with the medium power caliber ammunition of the rifle, thus in practice creating a submachine gun with body armor penetration capability. [5] Machine pistol A handgun-style firearm, capable of fully automatic or burst fire. They are sometimes ...
