Aero Precision APVG100007A VG6 Gamma 7.62mm 5/8"-24 tpi 2.21" Black Nitride 17-4 Stainless Steel

The VG6 Gamma is a muzzle brake and compensator hybrid that virtually eliminates recoil and minimizes muzzle movement. Its unique chamber geometries give it a very soft feel in the shoulder, and the gas ports' dimensions have been strenuously tested to give the utmost control to the muzzle.
This model is constructed of 17-4 heat-treated stainless steel with a black nitride stain (half-gloss) finish, 5/8x24" RH threads, and includes the crush washer. It is compatible with 7.62mm calibers.
