Sig's MCX is an innovative weapon system built around a battle-proven core. 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. It 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. This kit comes assembled with the 300 Black Out barrel and an extra barrel chambered in .223/.556 NATO and piston rod for this caliber. Included is one thirty round magazine.
