LanTac Dragon Muzzle Brake Features The LanTac Dragon muzzle brake uses a patented Short Energy Pulse design to reduce the length of recoil impulse which keeps repeating shots from stacking their recoil energy on top of each other and knocking the shooter off target. This gives .223 Rem / 5.56 shooters dramatically reduced muzzle climb and recoil even under full auto fire keeping follow up shots on target and improving overall weapon control. The Plan-B compatible mount lets shooters attach the Plan-B HUB for quick suppressor mounting though LanTac notes this mount is not licensed from Q so suppressor manufacturer warranties may be affected by its use. Each brake ships with a timing shim set for precise alignment during installation. Machined from 4140 steel on Swiss lathes for tight tolerances the Dragon brake is hardened to 55Rc and QPQ nitrided to AMS2753D standards giving it strong resistance to corrosion and extending its service life under hard use. The black finish matches standard AR-platform furniture and at 1.75 inches long with a 1/2x28 thread pitch it fits standard .223 Rem / 5.56 barrels without excess length. Each unit is serial numbered for quality control and LanTac recommends a semi-permanent thread locker sold separately for secure installation. Built and assembled in the USA this muzzle brake suits shooters seeking enhanced control for sale at GrabAGun.
