Midwest Industries Alpha Tank Brake Features The Midwest Industries Alpha Tank Brake uses a dual chamber design to redirect propellant gas in a way that significantly reduces muzzle rise helping shooters stay on target for faster follow up shots. Machined from 416 stainless steel the brake is built to withstand the heat and pressure generated by repeated firing without losing its dimensional precision over time. The black nitride finish adds a layer of corrosion resistance while giving the brake a dark low glare appearance that matches most AK finishes. At 2.25 inches in diameter and 12 ounces the brake adds meaningful recoil control without excessively altering the balance of the rifle. Threaded for the M14x1 left hand pattern common to AK-47 platform rifles the Alpha Tank Brake installs directly onto a compatible host without needing a separate thread adapter. Midwest Industries manufactures the brake entirely in the USA and backs it with a lifetime warranty reflecting confidence in both the materials and the manufacturing process. The .410 inch diameter bore hole is sized to clear the bullet path on typical AK caliber barrels without disrupting accuracy. For AK shooters who want a proven reduction in muzzle climb from a durable American made brake the Midwest Industries Alpha Tank Brake is available for sale at GrabAGun.
