Abstract
Anti-bounce apparatus for an automatic cannon reciprocating bolt assembly which includes a bolt, a bolt carrier and bolt mounted locking lugs, comprises means defining engagement surfaces contoured for enabling the forward moving carrier to cam the lugs into bolt locking relationship with a cannon breech at increasing velocity, without bouncing, carrier energy loss being thereby minimized and firing of a chambered shell by a carrier mounted firing pin being assured. Further comprising the anti-bounce apparatus is a plurality of inertially actuated locking collets connected to the bolt carrier for causing, responsive to impact of the carrier with the breech at the instant of firing, frictional locking between the carrier and portions of the cannon fixed to the breech, rearward bouncing of the carrier relative to the locking lugs, with consequent premature or erratic bolt unlocking, being thereby prevented.
