The Yankee Hill Machine Mini QD muzzle brake (brand part number YHM-3109-1MB-28A) threads onto a 9mm-bore barrel with a 1/2-28 thread pitch. Made by Yankee Hill Machine, this compact brake keeps the mini profile short while still giving you a quick-detach interface for pairing with a compatible YHM suppressor mount. It is a practical everyday muzzle device for a 9mm pistol-caliber carbine or pistol, with the option to add a suppressor later without rethreading the barrel.
