An airgun system comprises a gas reservoir 3 of generally cylindrical configuration and having a gas dump valve 7 at a forward end, a gun barrel 1 with an associated chamber 2A within which the said reservoir 3 is slidably receivable, an abutment means 4 arranged between said barrel 1 and said chamber 2A, and a firing mechanism 6,10 for driving the reservoir 3 forwardly within said chamber 2A the arrangement being such that such forward movement of the reservoir 3 is effective to discharge said reservoir 3 by causing abutment of said gas dump valve if 7 against the said abutment means 4, whereby the valve 7 is opened and gas discharged from the reservoir 3 is effective to propel a missile through the gun barrel 1. |
