# Sig Sauer MCX Rattler - Guns For Sale

The Sig Sauer MCX Rattler is an ultra-compact firearm in the MCX lineup, chambered in .300 Blackout or 5.56 NATO with a 5.5-inch barrel. Its short-stroke gas piston system cycles reliably under adverse conditions and supports suppressed operation. The quick-change barrel system allows caliber swaps, and the monolithic upper receiver integrates an M-LOK handguard for mounting lights, lasers, or grips. Ambidextrous safety, charging handle, and magazine release suit both right- and left-handed shooters. A folding stock or brace reduces overall size for transport.
