SIG Sauer MPX Copperhead 9mm

The SIG Sauer MPX Copperhead 9mm, is a compact PDW with 3.5″ barrel. The MPX Copperhead features a monolithic Elite Series Cerakote® finish upper receiver, with an integrated stock knuckle lower, and a 3.5” barrel with integrated muzzle brake. The MPX Copperhead comes equipped with the new SIG SAUER Pivoting Contour Brace (PCB) giving pistol users a brace that easily adapts to the movement of the shooter’s arm with a patented swivel operation for perfect placement, that can be rapidly deployed.

Unconventional design, unmatched performance, and familiar AR handling, the SIG MPX redefines the subgun category with a new level of operator safety, in-field adaptability and proven reliability in the harshest environments. Completely ambidextrous, the SIG MPX is great for left- or right-handed shooters with its dual-sided selector switch, magazine release, charging handle and bolt release. The SIG MPX operates from a fully-closed and locked rotating bolt, offering enhanced reliability and safety in use. 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. The SIG MPX Copperhead comes with one 20rd magazine, but 30rd SIG Factory magazines are available. The combination of a small but stable platform, with 30rd capacity makes the MPX Copperhead a lot of firepower in a small package.
