Claim:
1. A recoil compensator for a firearm barrel having a threaded barrel end and an annular barrel shoulder adjacent the threaded barrel end, the compensator comprising: a muzzle brake adapted to mount to the threaded barrel end; and a jam nut adapted to mount to the threaded barrel end and operatively connected to the muzzle brake, the muzzle brake includes a cylindrical brake body and a tubular brake neck extending axially from the brake body, the brake neck having an outer threaded section and an inner threaded section configured to turn onto the threaded barrel end, the jam nut includes a tubular nut sidewall and a nut end wall, the nut end wall having a central axial threaded bore configured to turn onto the threaded barrel end, the nut sidewall having an inner threaded section turned onto the outer threaded section of the brake neck so that the jam nut can be manually rotated to traverse over the brake neck and the threaded barrel end when mounted to the barrel between a first position where the nut sidewall abuts the brake body and a second position where the nut sidewall is spaced from the brake body forming a gap therebetween and the nut end wall abuts the barrel shoulder such that the jam nut selectively locks the muzzle brake in position relative to the barrel, the nut side wall also has an annular flange extending axially therefrom, the flange configured to partially overlie the brake body and to enclose the gap between the brake body and the jam nut when the jam nut is in the second position.
