LANTAC Dragon Muzzle Brake DGN556B for AR15, M16 & M4 Rifles. Manufactured to the highest quality standards and featuring a patent pending design, the LANTAC DGN556B Muzzle Brake offers improved recoil management and muzzle rise over competitors' products. Its unique Short Energy Pulse system reduces length of recoil so that repeating shot energy cannot overlap and knock the shooter off target. Full auto fire is possible with massively reduced recoil and muzzle climb, meaning that all shots fall on target.
