LANTAC Dragon Dead Air Xeno Muzzle Brake 5.56x45mm NATO/.223 Remington 1/2x28 Nitride Black. 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. Shooters can now enjoy advanced weapon control with the ability to mount the Dead Air XENO HUB. Dragon brakes are precision manufactured on Swiss lathes and machined from AISI4150 steel that is then hardened to 48-52Rc (Rockwell C) and QPQ (Quench Polish Quench) Nitrided to AMS2753D standards for enhanced corrosion resistance and improved lifespan. The mount design is fully licensed from Dead Air therefore customers suppressor warranty remains unaffected. Users should follow shooting guidance for the XENO HUB as supplied by Dead Air.
