ABSTRACT:
A breech assembly for a muzzle loader. A breech block is fitted into the gunstock and receives the barrel. The breech block includes a first bulkhead disposed over the barrel breech end and has a first bore with an axis parallel to the barrel axis. The breech block includes a second bulkhead spaced from the first bulkhead creating a space there between. The second bulkhead has a second bore in axial alignment with the first bore and the breech block includes a vertically disposed chimney bore communicating between the bottom of the space and the outside atmosphere. A nipple is disposed in the bore facing the space and has a third bore sized to releasably receive a percussion cap. The nipple has a fourth bore communicating between the bottom of the third bore and the barrel interior. A cylindrical sliding sleeve is disposed within the second bore and is slidable between closed and retracted positions. The sliding sleeve has means in the sidewalls for the passage of gases therethrough from the nipple to the chimney bore when the sliding sleeve is in the closed position. A cylindrical firing pin assembly is disposed within the sliding sleeve and is slidable between closed and retracted positions. The firing pin assembly has an axial fifth bore with a firing pin slidably disposed therein and spring means for biasing it towards the nipple. A trigger assembly holds and releases the firing pin against the force of the spring means.
