LanTac™-USA LLC is a Texas company our flagship first product to revolutionize the market was the LANTAC™ Dragon Muzzle Brake DGN556B for AR15, M16 & M4 Rifles. We manufacture 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. Ultra Fast Attenuation of muzzle blast gasses means that Flash Signature is also reduced.
