NO MATTER THE CONDITIONS.

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.

A BREAKTHROUGH IN MODULARITY.

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 AR upgrade kit includes side-folding stock assembly and adapter.

SHOOTER MAKE READY.

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.
