The Sig MCX is used by many military special forces, law enforcement agencies and elite shooters across the world.  It is recognized for being rugged, reliable and accurate.

One of the most notable features of the MCX is the ability to swap calibers with a few simple quick changes.  The MCX can go from 5.56 nato to the hard hitting .300 blackout or even 7.62x39 mm quickly and easily.
The MCX uses Sigs robust and reliable short stroke gas piston system with rotating bolt.

The MCX features ambidextrous controls, a beveled flared magwell, metal cam path wear insert, keymod free float rail system and takes ar style drop in triggers (one of our Elf triggers would be a great choice)
