Abstract

An air gun includes a retainer pivotably connected inside the air gun and having a bullet abutment part that pivots into and out of a bullet-receiving chamber. The retainer is resiliently biased to pivot in a forward direction so that the bullet abutment part is urged into the bullet-receiving chamber. In a trigger rest position, a hollow inner barrel prevents a bullet and the bullet abutment part from entering into the bullet-receiving chamber. Upon pulling the trigger, the inner barrel moves in a forward direction to permit the bullet and the bullet abutment part to enter the bullet-receiving chamber where the bullet abutment part contacts and retains the bullet therein. Upon pulling the trigger further, the inner barrel moves in a rearward direction to capture the bullet therein while causing the retainer to pivot in the rearward direction to thereby move the bullet abutment part out of the bullet-receiving chamber.
