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.
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 3/4” continuous top rail. The upper is backwards compatible with any mil-spec AR lower, allowing you to upgrade your existing AR platform to the SIG MCX.
The SIG MCX stands as the first rifle built to be silenced from the ground up. It also accepts a broad array of accessories, enabling you to build a complete weapon system for any scenario or environment. The SIG MCX eclipses everything that has come before it.
