Lantac Dragon Dead Air Keymo Wolfman Muzzle Break - 300 AAC Blackout - Manufactured to the highest quality standards and featuring a patented design, the LANTAC DGN300B-WM 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. Shooters can now enjoy advanced weapon control with the ability to mount the Dead Air Wolfman KEYMO silencer to their firearms. 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. Ships with timing shim set. Users should follow shooting guidance for the Wolfman as supplied by Dead Air. Lantac recommends the use of semi-permanent thread locker Rocksett, sold separately.
