Patent ID: 7726228

Claim:
A clamp on muzzle brake for a plurality of firearm barrels with different diameters or tapers to provide a reduction in recoil forces and accommodate a plurality of different projectile paths, said muzzle brake comprising: A V-shaped base for cradling the bottom of any of said plurality of barrels along a longitudinal axis of said V-shaped base near a muzzle end of said barrel; A clamp portion for contacting the top of the barrel and attaching to the V-shaped base to secure the barrel therebetween such that said longitudinal axis of said V-shaped base is substantially parallel to a longitudinal axis of said barrel when clamped; a muzzle brake tube attached to the end of said V-shaped base, said muzzle brake tube comprising a plurality of oblong holes with a long and short axis; Wherein the long axis is parallel to a plane extending from the apex of the V of the V-shaped base thru the centerline of the barrel such that the holes will provide sufficient clearance for bullets exiting from any of said barrels having different diameters; Wherein the long and short axes of said oblong holes are substantially perpendicular to said longitudinal axis of said V-shaped base such that a corresponding projectile exiting the muzzle end of a clamped one of said barrels is capable of entering and exiting said muzzle brake tube without contacting said tube.
