LANTAC Dragon® Muzzle Brake DGN556B-DA™

Manufactured to the highest quality standards and featuring a patented design, the LANTAC DGN556B-DA™ 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.

For the first time shooters can now enjoy advanced weapon control with the ability to mount the entire range of Dead Air® Sandman® KEYMO™ silencers to their firearms.

The Sandman range of silencers are manufactured with solid welded Stellite® baffle cores and detachable front caps. Exteriors surfaces are Cerakote® finished for ultimate durability.

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.

Ships with timing shim set.

Lantac recommends the use of semi-permanent thread locker Rocksett, sold separately.
