The CMMG SV muzzle compensator is an effective single port brake designed specifically for .30 caliber AR style rifles. The large port presents a broad surface for gasses to impact against, which keeps the muzzle down and the sights on target. Installs easily to any barrel threaded with 5/8"-24 threads.
