The Tubb muzzle brake redirects a fired round's gases to work for, rather than against, the shooter. This is accomplished by way of the 5 specially shaped ports, which reduce the recoil experienced by the user as well as virtually eliminate muzzle rise. An optional lock nut (not included) may be used with the muzzle brake to further tune the unit for the best accuracy. Length 2 5/16"
Outside diameter 1 1/16"
Bore hole 6mm, 0.26"
Five port brake may be adjusted rotationally to eliminate side movement of the muzzle during firing
Using the optional muzzle brake lock nut (sold separately), the brake mave be moved forward and backward on the muzzle to tune vibration
