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.
