Featuring high-strength, CNC-machined steel construction with a matte black finish, the HuxWrx Safety Company QD 338 Muzzle Brake – M18x1.5 is a proprietary, dual-purpose muzzle device designed to serve as a recoil-mitigating standalone brake, as well as a suppressor mount for HX-QD Magnum Ti suppressors (not included). Precision-cut baffles quickly disperse excess gases to the top, bottom, and sizes of the muzzle for maximum recoil reduction when unsuppressed. Plus, integrated suppressor threads offer quick installation and removal of your favorite suppressor, while precision-machined wrench flats facilitate proper installation of the brake on your rifle. Compatible with M18x1.5 threads.
