Midwest Industries Alpha Tank Brake Features The Midwest Industries Alpha Tank Brake uses a dual chamber design to redirect propellant gas and reduce muzzle climb helping shooters stay on target between shots. Built from 416 stainless steel and finished in Black Nitride the brake resists corrosion and wear while matching the dark finish common on AK pattern rifles. A 2.25 inch diameter and a .410 inch bore hole keep the brake compact while accommodating the bullet path without baffle strikes. At 12 ounces it adds manageable weight to the muzzle end without significantly shifting the rifle s balance. The brake is machined for a 24mm thread pitch with compatibility also noted for M14x1LH and 1/2x28 9mm threading depending on the host rifle. That threading flexibility makes it a practical upgrade for AK-47 pattern rifles and other platforms sharing those standards. Midwest Industries builds the brake in the USA and backs it with a lifetime warranty for long term reliability. This brake suits AK shooters looking to tame recoil and muzzle rise for faster more accurate follow up shots.
