Introducing the SIG MCX™. Engineered for 300BLK. Built from the ground up to be silenced, light and short. A breakthrough in modularity. The result of years of toil and sweat, the SIG MCX is proof that the dawn of a new era doesn't happen overnight

The SIG MCX is an innovative weapon system built around a battle-proven core: SIG's gas-operated, short-stroke piston system. Trust it for the outstanding performance, no matter the conditions, that you've come to expect from the leading name in firearms.

AR-Style, Ambidextrous Control. No retraining required. The SIG MCX features a familiar, AR-style ambidextrous selector, bolt release, magazine release and charging handle.

A fully locked and closed rotating bolt system provides maximum safety.

Reduce recoil and fouling with the gas-operated, short-stroke piston system.

The two-position adjustable gas system allows the user to increase or decrease gas as needed depending on ammunition, use with a silencer, or adverse conditions.
