The air gun with a gas-driven piston consists of the body (1), barrel (2), cocking lever (3), piston rod (4) and air piston (5), trigger mechanism (7). The piston rod (4) and the air piston (5) are pushed by the gas piston (8) coming out of the gas cylinder (10) linked via the gas channel (13) with the closed cavity (12) containing the gas bulb (17) which releases the gas through the needle (16). |
