Sig Sauer unveils the SIG MCX Rattler, a rifle designed shorter than any M4 ever produced. Built at the request of elite military units, the SIG MCX Rattler offers M4 ballistics in a subgun-sized package. With a 5.5” barrel and overall length of only 16” when folded, the SIG MCX Rattler rewrites the possibilities for ultra-compact firepower.

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.

The Sig Sauer 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.
