Gemtech 5.56 ETM 3Port Muzzle Brake - SuppressorReady 5.56/.223 Brake, 1/2x28 Thread The Gemtech 5.56 ETM 3Port Muzzle Brake is a precisionmachined device that reduces recoil and muzzle rise on 5.56 NATO and .223 Remington rifles while remaining compatible with Gemtech's ETM mounting ecosystem. The threeport geometry channels gas to lower rearward impulse and speed followup recovery without adding unnecessary length or weight. Finished in durable black nitride and weighing about 2 ounces, the brake is built for repeated service and erosion resistance. Threaded 1/2x28 for common AR15 platforms, the unit mates with ETM adapters to provide repeatable suppressor alignment and reduce the risk of carbon lock when paired with ETM cans. Tight tolerances and a sealed engagement form yield a lowprofile, repeatable mounting surface that installs with standard tools. Designed for shooters who need balanced recoil management and suppressed compatibility, the Gemtech 5.56 ETM 3Port Muzzle Brake delivers rugged construction, efficient gas control, and easy integration into ETM quickattach setups. Verify thread fit and visually confirm baffle alignment and secure engagement before firing.
