Sig Sauer MCX Rattler Semi-automatic SBR 300 Blackout 5.5" Barrel Folding Stock

Rapid deployment, thin, agile, and precise.

This is the MCX Rattler. Featuring a 5.5" PDW barrel, the MCX platform has never been more compact or accessible.

Ready to go where-ever it's needed, the MCX Rattler has a thin, foldable stock for easy concealment and stowage.

This gun was designed from the ground up to be as discrete as possible while retaining all the capabilities of the MCX.

Free-floating M-LOK handguards matched with a PDW upper and a PDW Ultra Thin Folding Aluminum Stock, the MCX Rattler SBR is the ideal choice for fast-moving operators.
