US 4,867,039 A · Combination pump action autoloading rifle and shotgun

Abstract

A semiautomatic gun which can be used to fire two types of ammunition comprises first and second bolts and a selector assembly operated by a user of the gun. The selector assembly selectively permits loading and firing of one type of ammunition. The gun has only a single trigger for firing either of the bolts selected by the selector assembly and the gun may be a combination of a shotgun and rifle or any other desired configuration. Each of the bolts are movable in a forward and rearward direction when fired and have bolt lock-up bearings for preventing such movement at other times. A reciprocable forestock is provided with a forestock lock release. The forestock can be pumped by the operator to initially load a round of ammunition into the chamber selected by the selector assembly. A bolt selector block is also provided which is connected to the forestock and which catches a bolt lug of a bolt selected by the selector assembly whereby the selected bolt may be engaged by the block and moved rearwardly to permit insertion of ammunition. A gas tube is also operatively connected to the bolt selector block to move the block rearwardly whereby loading of ammunition may automatically be carried out after a first round is fired. Additionally, a feeder is provided for supplying ammunition to a position adjacent either of the chambers.
