Fully Automatic means when the trigger is depressed and held the gun will keep firing until the trigger is released.
Semi Automatic means that each pull the trigger the gun, will fire once.
Blow Back is the action on a Gas or Electric gun means the slide of the gun
will recoil when the gun is fired like an real firearm.
Airsoft Gun could
be divided into 3 major groups by supplied powers:
1. Spring powered
2.
3. Electric powered
Spring powered airsoft gun is a 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, just like you would do for a real
shotgun or bolt action rifle. This is
typically achieved by pulling back the slide of pistols or bolt of rifles that
compresses the spring and makes the gun ready to fire.
Gas powered airsoft gun uses pressurized
gas to propel BB pellets. The gun is capable of Automatic & Semi-automatic
operation. The most common gases used are propane(Green Gas) and HFC134a
refrigerant. Other 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 blow-back feature is desired.
Electric powered airsoft gun is usually using rechargeable
batteries, a motor
runs a gear box that compresses a cylinder compressing air which cycles an internal piston/spring assembly in order to launch BB pellet.
Automatic and Semi-automatic operation are all possible which gives the gun the
popular name Automatic Electric Gun(A.E.G).
C.Q.C stands
for Close Quarters Combat or C.Q.B stands for Close Quarters
Battle.
Both
are type of warfare in which small units or teams engage the enemy with
personal weapons at very short range.
Muzzle velocity is the
speed a projectile
has at the moment it leaves the muzzle
of the gun.
