US Patent 9958226 Systems and methods for providing a multi-shot firearm

The present invention relates to firearms. In some cases, the firearms include a firing pin; a first ignition chamber that is configured to house a round of ammunition and to move proximally with respect to the firing pin so that when the round is in the first chamber and the firearm is fired, a portion of the round is struck against the firing pin. In some cases, the firearms also include a follower configured to be movable proximally and distally within the firearm and to be biased against a primer or proximal end of the round such that the follower is configured to selectively hold the round within the first chamber as the first chamber moves proximally, and such that proximal movement of the follower stops when the round strikes the firing pin, so that the follower acts as a bolt face for the round. Other implementations are also described.
