The Sig Sauer MCX Rattler PDW chambered in 300 blackout is an ultra compact large frame pistol designed for personal defense. The legendary MCX is well known for it’s versatility, modularity and reliability. This diminutive little gun is quick to deploy and packs a big punch. The Sig MCX Rattler has a threaded 5.5” carbon steel barrel with a three prong flash hider surrounded by a free float M-Lok handguard. Sig uses a reliable short gas piston operating system that eliminates the need for a buffer tube giving the Rattler a more compact form than competitors. Of course this is a pistol so Sig uses a folding pivoting contour pistol brace for added stability. The MCX Rattler features an ambidextrous mag release and safety along with a Sig Sauer Enhanced Trigger. The MCX uses standard AR15 magazines. One 30 round polymer magazine included.
