Abstract (en)
A muzzle cover for fire arms of the type having a barrel (5) through which a shell or a similar projectile is intended to be launched. The muzzle cover is made of an elastic material and comprises a collar (12) which carries a flexible diaphragm (13) and which is adapted to be pushed over the muzzle of the barrel (5). The diaphragm (13) is bowed concavely inwards and is integral with the collar (12) over a recess (15) which is bowed convexly outwards and has a reduced thickness of material as compared with the diaphragm (13). The recess (15) provides a kerf for removing the diaphragm (13) when the pressure in the barrel (5) has increased to a predetermined level when the shell or similar projectile is launched. The collar (12) is slightly conical so that the muzzle cover can be forced onto the barrel, and the collar (12) has a successively reduced thickness in the direction rearwardly.
