NLX-31 Salvation .338 Compensator The NLX-31 Salvation .338 Compensator from Next Level Armament directs the majority of the muzzle blast to the sides reducing recoil, while small ports on the top keep muzzle rise to the minimum. The reduced recoil and barrel rise combine to reduce the time needed to reacquire your target while increasing the accuracy of follow-up shots.. A solid underside makes sure no dust or dirt flies up into your face while shooting from the prone position. Threaded 5/8-24 with a bore diameter of .373, we designed the NLX-31 for use with calibers up to .338. We turn each compensator from solid stainless steel bars, then finish on the mills for exact tolerances. Next is a QPQ coating for a long lasting finish. Includes a crush washer. 5/8-24 TPI overall length 2.25' .338 Caliber
