SIG SAUER® MCX® Rattler PSB .300 AAC Blackout Semi-auto AR Pistol
Rapid deployment, agility and precision: this is the SIG MCX® Rattler. Built around a cool, clean gas piston system, PDW upper, and 5.5" barrel, the MCX platform has never been more compact or versatile. Ready to go wherever it's needed, the MCX Rattler PSB features a 3-position telescoping pistol brace for stability and easy concealment. This gun was designed from the ground up to be as discrete as possible while retaining all the robust capabilities of the MCX. Polished off with a free-floating M-LOK® handguard, the MCX Rattler PSB is the ideal choice for fast-moving operators.
