New Sig MCX Rattler 5.5” 300 BlackOut with PCB Brace
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. Ready to go wherever it’s needed, the MCX Rattler PCB in 300 BLK features a folding pivoting contour 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.
