Rapid deployment, thin, agile and precise. This is the SIG MCX Rattler. Featuring a 5.5″ PDW barrel, the MCX platform has never been more compact or accessible. This gun 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 is the ideal choice for fast-moving operators.
