Midwest Industries MIMB6 Muzzle Brake - Black Phosphate Steel, M14x1 LH Threads, for 30 Cal AK-Platform

The Midwest Industries MIMB6 muzzle brake is a two-chamber design purpose-built for 30-caliber AK-platform rifles and pistols. If you're running an AK in .308 or 7.62×51 and want to tame recoil and muzzle rise without the tax stamp, this is a straightforward, domestically-made solution. The large-port design helps redirect gas to manage the impulse typical of full-power rifle rounds on the AK platform.

Midwest Industries has been making precision-machined parts since 2003 with a focus on American manufacturing and real-world utility. The MIMB6 comes in black phosphate steel—a finish that handles the carbon and heat of repeated firing without fussing, and it threads onto AK barrels with M14×1 left-hand threads, the standard for most AK-pattern rifles and short-barreled pistols in this caliber.

Whether you're running a standard AK rifle, an AK pistol, or an SBR build, this brake gives you a no-fuss way to reduce felt recoil and keep your sight picture stable between shots. Install it, apply appropriate threadlocker, and move on. No permanent modifications, no paperwork—just functional, made-in-America hardware.

Frequently Asked Questions

Will this fit my AK rifle or pistol?

The MIMB6 is compatible with 30-caliber AK-pattern rifles and pistols that have M14×1 left-hand threaded barrels. This is the standard thread spec for most AK-platform guns in .308 and 7.62×51. Verify your barrel's thread specification before purchase.

What does black phosphate finish do?

Black phosphate is a chemical conversion finish that resists corrosion and handles heat well. It's common on combat-grade and working firearms because it's tough, low-maintenance, and won't degrade under field use and carbon buildup.

Is this brake legal?

A muzzle brake itself is not federally regulated and requires no paperwork or registration. However, some local and state jurisdictions have restrictions on muzzle devices. Check your local laws before purchase.

What's the difference between a two-chamber design and other brake types?

Midwest's two-chamber design uses internal porting to redirect expanding gases and manage recoil impulse. It's a proven approach for AK-platform rifles, balancing recoil reduction with a compact footprint and reasonable price.
