SIG Sauer ~ MCX ~ 5.56X45mm NATO

The SIG Sauer MCX is a versatile semi-automatic rifle featuring an older-generation configuration with a 16-inch barrel, KeyMod handguard, and collapsible stock. Its short-stroke gas-piston operating system provides reliable function while allowing the action to operate without a traditional AR-style buffer tube. The lightweight KeyMod handguard offers attachment points for compatible accessories, while the full-length upper rail provides ample space for mounting optics and sights. A three-position collapsing stock attaches through the receiver's 1913 interface, allowing the rifle's length of pull to be adjusted while maintaining a compact, streamlined profile. With its modular construction, ambidextrous controls, and distinctive early-production features, this MCX is a desirable option for collectors and shooters who appreciate the original generation of SIG's modern rifle platform. In good shape with some use and wear.
