Product Summary

The SIG MCX is engineered for .300 BLK and built from the ground up to be silenced, light, and short. The MCX is an innovative weapon system built around a battle-proven core: SIG's gas-operated, short-stroke piston system. Even while in the field, you can configure the SIG MCX as needs or conditions change. The combination of the 13" monolithic upper receiver and handguard create a 17.75" continuous top rail. The MCX can also be converted to 5.56 NATO or 7.62x39mm with just a few component changes. The upper is backwards compatible with any mil-spec AR lower, allowing you to upgrade your existing AR platform to the SIG MCX.

The continuous-to-rail upper receiver on the MCX features an integral M1913 rail at 12 o'clock and a free-float barrel system. Additional features include: a beveled and flared magwell, a metal cam path wear insert, a KeyMod aluminum alloy handguard, and multiple integral QD sling points. The SIG MCX Carbine has a folding stock for easy transport. Ambidextrous controls. 1 in 6" twist. This model also includes a Romeo 4B Red Dot Sight.
