10 Gauge Custom Sliding Breech Mechanism

10 Gauge Custom Sliding Breech Mechanism

The Typical U.S. Artillery Style ‘Sliding Block Breech’
The B.N.A. sliding breech block opens and closes easily. It is a U.S. breech loader design which offers mechanism simplicity and is also sophisticated and safe. The breech block slides to the side to open (but it could be manufactured to slide in another direction). Both the “open/loading position” and the “closed/firing position” of the breech block are held snugly in place by cam pin pressure. A spring loaded cam pin prevents unrestrained sliding motion of the breech block. The sliding breech block stays attached to the cannon.
