Interestingly, MI puts detent-indexing cutouts at all four quarter-turns. However, from the shooter’s perspective it’s no louder than the stock slant brake. As expected, the MI 2-Chamber muzzle brake is quite loud from the side. It’s a large port design with a bigger main port and a slimmer second port in front with three small venturi in-between. Their AK Two-Chamber muzzle brake is the only true muzzle brake in this round up, as it doesn’t vent any gas upward to push the muzzle down. (Firearms News photo)įor a number of years now, Midwest Industries (MI) has been making good quality AK handguards at an attractive price point. Midwest Industries AK Two-Chamber Muzzle Brake The Midwest Industries Two-Chamber muzzle brake is a traditional big port design that’s a blend of high-efficiency and good value. The tradeoff of the small port design is it’s harder to design it to be effective, and since it needs more ports to get the same recoil reduction, it’s more expensive to manufacture. The small port design in general is quieter, with a softer side blast, and produces less flash. However, the large port design is very loud, typically produces a large concussive blast and a very bright flash. Most select the large port design because it’s highly effective, easy to develop and economical to manufacture. There are essentially two major types: large port and small port. What really matters to me is the port design of a muzzle brake/compensator. Most of those labeled as compensators do more to reduce recoil than to keep the barrel flat. The majority of muzzle brakes nowadays have venting ports added to the top or have angled some of the ports upward to provide the function of a compensator. Today, the distinction between a muzzle brake and a compensator gets a bit blurred. Adding an effective muzzle brake or compensator can reduce recoil and muzzle rise, the trick is picking the right one. This added the function of recoil reduction by pushing the gun forward during firing. Eventually a true muzzle brake was introduced with the fielding of the AK-74. It’s not really a brake, as it’s essentially a compensator that pushes the barrel down by directing some of the propellant gas upward. They added a simple slant brake in 1959 with the AKM update. When the Soviets introduced the AK-47, they didn’t bother to include a muzzle device.
