The LANTAC Dragon Muzzle Brake has vertical ports in the primary discharge chamber to counteract muzzle rise, while the Short Energy Pulse system decreases recoil length, preventing stacking of repeating shot energy and enabling fast, accurate follow-up shots. Even with fully automatic fire, the Dragon delivers significant reduced recoil and muzzle climb, so more shots land on target. Machined from ultra-hard steel, the Dragon is virtually impervious to heat, corrosion and wear. Flats on the side allow you to install it with any standard wrench. Includes crush washer for secure fit and proper indexing.
