The Midwest Industries Two-Chamber Muzzle Brake (brand part no. MI-MB4) is a direct-thread recoil control device built for 5.56 NATO/.223 Remington AR-15 rifles running standard 1/2×28 threads. Machined from steel and finished in black, its dual-chamber port design vents propellant gas outward to reduce felt recoil and flatten muzzle rise, keeping your sight picture on target for faster follow-up shots. It’s a simple, durable bolt-on upgrade for any AR-15 owner who wants a softer-shooting rifle for range days, competition, or hunting without adding significant length or weight up front.
