It has a fully ambidextrous magazine release, safety selector, and bolt catch. The MCX-REGULATOR ships with a two-stage match trigger, a cold hammer-forged carbon steel barrel, a SIG-designed muzzle brake, and is available in 7.62x39 and 5.56 calibers. The MCX-REGULATOR offers a built in Arca Rail for easy tripod mounting and ships with a 10-round magazine.
