Air gun for shooting a bullet by supplying compressed gas and performing blow-back for shooting the next bullet by moving a sliding portion backwards in the gun

摘要

A bullet store (5) is located in the lower portion of the barrel (2) and a columnar hit pin (9) is inserted from the muzzle side (D) into a rear through hole opposed to the cylinder (8). The hit pin is pressed by a hammer (10) on a hammer shaft (11) and compressed gas from a bomb (A) is fed into a valve pin chamber, to bias the valve pin (39) to the gun rear end side, so that its flange portion and the chamber form an airtight connection. To operate the gun, a slide (3) is moved to the rear and the pressure is released, to fire the bullet when the hammer strikes the hit pin.
