Safety mechanism for blowback firearm
12313364 · 2025-05-27 · ·

A breechblock assembly for a firearm includes a breechblock extending along a central axis and configured to reciprocate along a receiver of the firearm between a recoil position and a battery position. A lever on the breechblock is movable from a blocking position to a non-blocking position in response to the breechblock moving from the recoil position to the battery position. A spring biases the lever to the blocking position. When the lever is in the blocking position the lever prevents the firearm from firing.
