Knights Armament 30169 QDC MAMS Muzzle Brake Kit Black with 3/4-24 tpi Threads & 3.10 OAL for 7.62x51mm NATO AR-Platform

The Knight's 7.62 MAMS (Multi-Axis Muzzle Stability) Brake has been engineered to increase controllability, to significantly reduce felt recoil and to help mitigate a rifle's flash signature as compared to traditional muzzle brake designs. The MAMS is a neutral bias brake that combats both muzzle rise and drift upon firing. Depending on the gun's barrel length, it can reduce felt recoil in a 7.62x51mm gun by as much as 52 percent. The 7.62 MAMS is compatible with KACs Quick Disconnect Coupling (QDC) 7.62mm sound suppressor line and comes complete with a 7-piece shim kit and installation instructions.
