Buy Sig Sauer MPX 9mm Semi-Automatic 30rd. With the unconventional design, unmatched performance, and familiar AR handling, Sig’s MPX redefines the submachine gun category with a new level of operator safety, in-field adaptability, and proven reliability in the harshest environments. With ambidextrous controls, the MPX is great for left or right-handed shooters with its dual-sided selector switch, magazine release, charging handle, and bolt release.

A short-stroke gas piston allows the SIG MPX to run all weights and brands of 9mm ammunition with no adjustments to the gas valve. A full-length Picatinny rail allows for solid, consistent mounting of optics and targeting lasers.

This model comes with a side-folding Pistol Stabilizing Brace and a black finish on the synthetic pistol grip, hard coat anodized receiver, and full-length aluminum key mod handguard.
