Gemtech Muzzle Brake Features The Gemtech Muzzle Brake features Quickmount lugs compatible with all 5.56mm and 7.62mm Gemtech suppressors allowing fast secure suppressor attachment without additional adapters or tools. An extended section behind the lugs accommodates shorter barrel configurations while built-in carbon cutting grooves help clear carbon fouling from the suppressor interface for reliable repeatable suppressor seating. Increased 3/4 wrench flats make installation straightforward and secure with standard tools. A Blank Firing Adapter groove provides compatibility with GMT/GM-HALO and training devices making the 5.56mm Muzzle Brake a practical choice for both live fire and training applications. The 2.4 overall length is optimized for 14.5 barrels and comes pre-drilled for pinning to meet legal overall length requirements. A precision mounting shim kit is included to ensure a flush secure fit on the host barrel with every installation. Gemtech has built its reputation on producing precision-engineered suppressor accessories and muzzle devices that integrate seamlessly with their suppressor platforms. The Muzzle Brake continues that tradition with a versatile feature-packed muzzle device that delivers practical recoil reduction and Quickmount suppressor compatibility in a single package. It stands as one of the more capable and well-appointed muzzle brakes available for shooters running Gemtech suppressor systems.
