Product Description

LANTAC DGN556B-ASR Dragon Advanced Muzzle Brake with SilencerCo ASR Quick Mount Suppressor Adapter. The DGN556B-ASR is precision machined, hardened to 48Rc and nitride finished for enhanced corrosion resistance. It features Lantac's 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 SilencerCo ASR quick mount system it is now possible to mount the SilencerCo Saker, Omega Suppressors and the Blast Shield. The DGN556B-ASR Brake/ Mount is threaded 1/2-28UNEF and is designed to be used with 5.56/.223 Caliber ammunition only.
