Sig Sauer MCX 300 Blackout Semi Automatic Rifle with 5.56mm NATO Barrel
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.
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.
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.
