Manufactured to the highest quality standards and featuring a patented design, the LANTAC DGN762B-DAX 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 XENO HUB.Features :Short Energy Pulse SystemIncludes Timing Shim SetXENO HUB Thread
