Gemtech 13817 | 7.62 ETM 3-Port Muzzle Brake

The Gemtech ETM 3-Port muzzle brake (MPN 13817) is built to align reliably with Gemtech ETM-style suppressors and to reduce the chance of carbon lock when a suppressor is attached. Its compact profile and pre-dimpled mounting make it suitable for installation on rifles requiring a 5/8-24 mount and pin-and-weld attachment to a 14.5″ barrel. Typical applications include precision or target shooting with suppressor-equipped 7.62 rifles and range work where suppressor alignment and consistent muzzle devices are important.
