The Sig Sauer SIG MCX Rattler PCB Rifle provides the SIG MCX in a discrete, concealable platform. Featuring a folding pivoting countour brace and a 5.5″ barrel with PDW upper, the MCX platform has never been more compact or accessible. Rapid deployment, thin, agile and precise. This is the SIG MCX Rattler. The MCX Rattler was designed from the ground up to be as discrete as possible while retaining all the robust capabilities of the MCX. Free-floating M-LOK handguards matched with a PDW upper and 5.5″ barrel, the MCX Rattler PCB is the ideal choice for fast-moving operators.
