Abstract: A damper for an air gun has a gas spring at least partially disposed within a compression tube. The damper includes a damping component contacting the gas spring and the compression tube. The damping component damps vibrations in the air gun when the gun is fired.

Abstract: A gas spring having an internal vibration damper for an air gun charging system. The gas spring including a relatively thin liner which is received within and abuts the elongated inner and/or outer wall of the tubular gas spring. The liner(s) absorbs vibration in the air gun to improve firing performance. A guide sleeve mounted to the outer surface of the gas spring abuts an air gun's tubular compression piston to transfer any vibrations in the compression piston to the liner. A tubular counter-weight is slidably mounted about the outer wall of the gas spring and strikes a forward end of the charging system after the air gun is fired to counter the post-firing recoil.

Abstract: This invention is related to a kit to retrofit a mechanically spring-powered air gun to a gas spring-powered air gun, and to a self-contained gas piston for an air gun. The gas piston has a center latch which engages the center latch operated by the trigger.

Abstract: A base for mounting an elongated telescopic sight on a gun which experiences a sudden reaction when a projectile is discharged from the gun. The gun has a pair of resilient leaf elements each supporting a sight mount to reduce the reactionary motion experienced by the sight.
