The above
described method is common to most airsoft gas guns. Has
disadvantages such as the need for taking a bottle or
problematic firing at lower temperatures. A huge plus is
realistic weapon functions. These, mostly metal, replicas have
internal trigger mechanism very similar to the real one. The
gun has a real field take down, require cleaning and
lubricating. When you insert magazine, you have to pull
receiver and load first BB from the magazine to the chamber.
For each shot there is a subsequent 'kick' back and reloading.
The gun can shot semi or full auto. It provides great metal
clicking sound and mild recoil. After shot out all bullets
from the magazine (which usually has a more or less real
capacity), the receiver remain as a real weapon in the back
position.
This
presented gun works as has been described above. The body is
manufactured on CNC machined from a block of aluminum alloys.
The barrel is (to increase the weight) made of steel. Many
parts are obviously taken from real weapon. Sights, pistol
grip, stock, receiver cap...etc. The selector switch works
exactly as a real weapon.
