LANTAC DGN556B-QM™ Dragon® Advanced Muzzle Brake with
Gemtech™ Quick Mount Suppressor Adapter.

Designed for use with .223/5.56 Caliber Ammunition.

The DGN556B-QM™ is precision machined, hardened to 48Rc and Nitride finished for enhanced corrosion resistance.

It features our patented gas handling system that reduces muzzle rise and recoil to zero, meaning that the only recoil felt by the shooter is from the movement of the carrier and buffer within the buffer tube.

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.

With the addition of the Gemtech™ quick mount system it is now possible to mount any of the Gemtech™
Bi-lock suppressors to our brake. This includes ‘The One’ suppressor, Shield and older G5 models.


Comes with appropriate shim set for timimg the brake / mount. X2 .34mm, X3 .22mm, X3 .11mm, X4 .075mm & x1 2mm Washer. We recomend the use of Rocksett thread locker that is not included.
