Muzzle recoil dampener

Claim 1

In a gun barrel, an improved muzzle dampening or brake device having a housing with a pair of diametrically opposite gas emission outlets mounted thereon which outlets extend substantially normally to the longitudinal axis of the gun barrel, said device is adapted to be coaxially mounted on the muzzle end of a gun barrel, the improvement comprising: (a) the interior diameter of said muzzle dampening or brake device is identical to the caliber of the gun barrel; (b) said device having a plurality of through-bores for placing the interior of the device in communication with the ambient atmosphere, the through-bores are equiangularly disposed about the axis of the device in a plurality of parallel planes which are normal with respect to the longitudinal axis of the gun barrel; (c) a plurality of annular parallel grooves disposed on the outer periphery of the device normally with respect to the axis of the device, each of said grooves being in communication with the through-bores disposed in one of said parallel planes; (d) said device is of cylindrical shape, said housing being coaxially gas-tightly mounted over said device, said housing having a pair of diametrically opposite horizontally projecting extensions defining said pair of opposite gas emission outlets which are in fluid communication with said plurality of annular grooves; said housing having a sufficient axial length so as to cover all of said annular parallel grooves.
