The Midwest Industries Two-Chamber Muzzle Brake (brand part no. MI-MB5) is a direct-thread recoil control device built for .30 caliber AR-platform rifles running 5/8×24 threads. Machined from steel and finished in black, its dual-chamber port design redirects propellant gas outward to cut felt recoil and keep the muzzle flatter between shots, which means faster follow-up shots on steel or game. It’s a straightforward, durable upgrade for shooters running .308 Win, 300 Blackout, or other .30-caliber AR builds who want a noticeably softer-shooting rifle without switching to a muzzle-heavy compensator.
