Abstract
A hangfire protection system for an externally powered gun includes a recoil sensing mechanism cooperating with a sear latching mechanism such that in the event of a hangfire, a sear engages a safety link on the chain drive assembly to keep the bolt locked. If the round fires, gun function continues; if the round does not fire there is a delay of a sufficient time to assure that the round is a dud, and it is ejected. The details of the mechanical hangfire protection system are described.
