This Compensator was designed for tactical applications to reduce muzzle rise, flash signature, noise, and lateral pressure. It is compatible with A2-mounted suppressors due to unique external geometry. Tuned slots and interior cone offer maximum in recoil mitigation, muzzle-rise compensation, and flash reduction. It is a dual action brake that minimizes side pressure, and is designed to have less noise in comparison with typical compensators – perfect for working in teams for CQB. Stainless Steel construction offers maximum corrosion resistance, and a predrilled hole in the base affords permanent installation. Threaded 1/2 x 28 for 5.56mm AR15 platforms. A Crush Washer (included) for correct port timing is required and installation should be performed by a qualified military armorer.
