Abstract

A clip and indexing mechanism for a gas-operated gun which affords the visible inspection and incremental advancement and insertion of projectiles from the clip into the chamber of the gun. The clip is formed with a long narrow rectangular web across which are positioned parallel spaced cylindrical cavities, each containing a projectile and each cavity being individually sealed by a mechanically rupturable seal. The gun includes an indexing mechanism for indexing the clip but reciprocation of the breech block to withdraw a bolt or obturator from the clip, index the clip and then force the next projectile through the seal and into the bore also cocks the hammer and further reciprocation before firing the projectile then in the barrel does not operate the indexing mechanism. Releasing the hammer resets the indexing mechanism to index the clip. The breech block is reciprocated after firing, and this motion cocks the hammer and operates a lever to reciprocate a pawl and index the clip through an opening in the housing extending transversely of the barrel. The clip is formed of a translucent polymeric material permitting the visible inspection of the color of the projectiles therein. The gun has a high pressure gas valve with two chambers and two outlet valves leading to different barrels for firing different projectiles.
