Product Description The LanTac USA LLC DGN556B-QM Dragon Advanced Muzzle Brake with Gemtech Quick Mount Suppressor Adapter represents a significant advancement in muzzle device technology for .223/5.56mm caliber rifles. Precision machined from hardened Mil-Spec steel to 48Rc and finished in a durable nitride coating, this muzzle brake delivers exceptional corrosion resistance and long-lasting performance. LanTac&';s patented gas handling system effectively reduces muzzle rise and recoil to near zero, ensuring the shooter only feels the movement of the bolt carrier group and buffer within the buffer tube. The unique Short Energy Pulse system further shortens the recoil impulse so that successive shots do not compound and knock the shooter off target - even during full-auto fire. Threaded at 1/2"x28, this device also incorporates a Gemtech Quick Mount adapter, enabling seamless attachment of any Gemtech Bi-Lock suppressor, including The One, Shield, and older G5 models. Serial numbered for quality control and made in the USA.
