LANTAC Dragon Plan-B Hub Mount Muzzle Brake DGN556B-PBL
Manufactured to the highest quality standards and featuring a patented design the LANTAC DGN556B-PBL 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 Plan-B HUB.
Dragon brakes are precision manufactured on Swiss lathes and machined from AISI4140 steel that is then hardened to 55Rc (Rockwell C approx) and QPQ (Quench Polish Quench) Nitrided to AMS2753D standards for extreme use enhanced corrosion resistance and improved lifespan.
The mount design is not Licensed from Q and therefore suppressor warrantly will be effected.

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