Designed for the discriminating shooter and professional end-users, The ECHO-556 Tactical Brake brings you the best recoil mitigation the industry has to offer. This is a true combo style muzzle brake / compensatory / flashhider. It is the only muzzle brake that can substantially reduce muzzle flash while retaining full recoil-reducing properties. Features Extended flash hiding prongs and no ports at the 12 o’clock positions allow uninhibited view from flash through optics or sights. The difference in porting is also noticed on the underside of the device where it has 6 valve holes to allow the fastest gasses reaching the second chamber to exit. This creates very soft low energy recoil that allows for absolute control. Extremely flat shooting
