Compact and purpose-built, the Gemtech 13817 7.62 ETM muzzle brake provides a factory-specified interface for ETM-series suppressors while retaining a short profile suitable for restrained overall barrel length. Its pre-dimpled construction simplifies pin-and-weld attachment on a 14.5″ barrel and the 3-port layout addresses gas routing and buildup concerns encountered with suppressed use. This brake is appropriate for suppressed precision shooting and range applications where a secure ETM alignment and minimized carbon locking are priorities.
