Knight’s Armament is close to shipping the 5.56 MAMS muzzle brake kit according to a post on the company’s site. The brake is said to reduce felt recoil by up to 67% depending on the length of barrel. MAMS stands for Multi-Axis Muzzle Stability.
The brake also reduces the flash signature and is compatible with the company’s QDC line of sound suppressors. The brake weighs 2.6 ounces and is a little more than 2″ long.
