Abstract: A compressed gas weapon (10) is configured in the breech portion (18) of its barrel (12) to accommodate a projectile (24) in a position of readiness to fire and to reproducibly caliber the projectile (24) in the process of conveying it into the position of readiness to fire.

Abstract: A low-recoil gun (10), in particular a compressed-air gun or hand firearm, is proposed, comprising a stock assembly (25) and a barrel assembly (20) displaceable relative to the stock assembly (25) in the longitudinal direction (B) of the gun (10). The barrel assembly (20) can be moved contrary to the direction of fire (A), on the occasion of a discharge, out of a position of readiness to fire. The reverse travel of the barrel assembly (20) due to the discharge is restrained by an locking device (40) capable of being overcome by the recoil energy of the barrel assembly (20). In overcoming the locking device, the barrel assembly (20) performs work, which is deducted from the recoil energy, so that the recoil ultimately transmitted to the gunner is at least substantially reduced. In the gun according to the invention, the axial force required in longitudinal direction (B) of the barrel to overcome the locking device (40) is adjustable.
