ABSTRACT:
A closed breech rocket gun has a tubular bolt with an outwardly extending lug thereon for locking the bolt in its forwardly projected position as the lug is shifted into engagement with an abutment wall on the receiver by means of a bolt operating plate guided thereon. The bolt operating plate effects retracted and projected movements of the bolt and locks it against the rear portion of the firing chamber at the rear portion of the barrel as it engages the lug in the projected position of the bolt.
