Sig Sauer

Unconventional design. Unmatched performance. The SIG MPX™ redefines the submachine gun category with a new level of operator safety, in-field adaptability and proven reliability in the harshest environments. There’s nothing else like it. And it’s only available from SIG.

The Sig MPX operates with a fully closed and locked rotating bolt system, which greatly enhances operator safety. The MPX also employs Sig's battle-proven gas-operated short-strock piston system for unequalled reliablity in the field even under the most adverse conditions

The Sig MPX is the only submachine gun that allows the operator to change the barrel length and stock configuration in the field to meet mission requirements.

Familiar AR-Style controls w/ambidextrous safety/selector, magazine release, and bolt catch allows the operator to smoothly transition from his/her battle rifle to a SBR/SMG seamlessly

The bold is held open on on the last round fired.
