Abstract
A semiautomatic shotgun having a gas operating mechanism for unlocking a bolt and moving it from battery position. The operating mechanism includes an action bar and an inertia weight assembly which comprises a plurality of inertia elements. The inertia elements, the action bar and the bolt are arranged for movement relative to each other and impact at different times during the operating cycle. A return spring cooperates with the inertia weight assembly to maintain the various parts of the mechanism in fixed position relative to each other when the bolt is locked in battery.
