LANTAC Plan-B Dragon Muzzle Brake 338 ARC 5/8-24 Short Black. 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.
