SIG SAUER MCX 5.56MM CARBINE/ RIFLE
The SIG Sauer MCX is without question one of the most adaptable and customizable firearms currently available. It promises shooters the ability to easily transition between three different popular cartridges using supersonic or subsonic loads—with or without a suppressor—and it has an innovative and reliable gas-piston system that makes all of these things possible.
The SIG MCX is primed for user-customization, with ample optics options available courtesy of 17¾ inches of available rail space up top, a KeyMod handguard for accessories, and several unique folding and expanding stock options from SIG. The MCX is a modular, multi-caliber weapon platform that users can transform into whatever they need it to be.
