JMac Customs 360HD KeyMicro 1/2x28 FD Facemount KeyMount

The JMac Customs 360HD KeyMicro 1/2x28 FD Facemount KeyMount is a heavy-duty muzzle device designed for recoil control and suppressor protection. Designed to work with firearms chambered for high-pressure cartridges, this unit integrates the recoil-reducing characteristics of a traditional brake with Dead Air KeyMicro quick-detach compatibility for use with KeyMo and KeyMicro-equipped suppressors. Built from 17-4 PH stainless steel and treated with a QPQ Black Nitride finish, this muzzle device is resistant to erosion and corrosion under high-volume use. Its graduated port layout and three internal sacrificial baffles efficiently redirect gas and help shield attached suppressors from blast damage. Installation is straightforward, with no timing or shims required—just a standard 3/4" socket. This muzzle brake is suitable for use on short-barreled firearms and does not require a minimum barrel length. It is made in the USA.
