Product Description The LANTAC USA Dragon Muzzle Brake (DGNAK47B) is a precision-engineered muzzle device designed specifically for AK-47 rifles and variants chambered in 7.62x39mm. CNC machined from hardened Milspec steel and finished in a durable black nitride coating, this muzzle brake delivers superior recoil management and muzzle rise control that outperforms competing products. Its innovative Short Energy Pulse system attenuates the length of recoil so rapidly that repeating shot energy cannot overlap, preventing the shooter from being knocked off target. Whether running in rapid semi-auto or full-auto, the Dragon keeps rounds on target with dramatically reduced recoil and muzzle climb. As an added benefit, the ultra-fast attenuation of muzzle blast significantly reduces flash signature. Serial numbered for quality control, the DGNAK47B ships with an appropriate crush washer and installs on a standard 14x1MM left-hand thread. Made in the USA.
