The Yankee Hill Machine Mini QD Brake is a muzzle device for 9mm barrels threaded 5/8x24, the common thread pitch for pistol-caliber carbines and AR-9 builds. A compact muzzle brake helps tame recoil and muzzle rise for faster follow-up shots, and the quick-detach design lets you swap devices more easily. YHM has been making AR-pattern accessories for years and is known for solid, affordable hardware.
