MUZZLE ATTACHMENT.
A steel muzzle attachment for ball firing is provided to assist recoil. When attachment is fitted on gun, the gland replaces the packing gland. The muzzle cup is fixed to barrel by a clamping screw, body of which lies in a circular groove on barrel, thus preventing muzzle cup from being blown off should clamping screw become loose. Outer casing is attached to gland by an interrupted flange and spring-keeper pin. Front cone screws into front end of outer casing, and, to protect its face from erosion, is covered by a thin steel disc, which, when badly eroded, can be replaced by a spare one. Gland and front cone have flanges which are grooved to receive the combination tool provided for assembling and stripping purposes.
