The Sig Sauer MPX K redefines the submachine gun 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 choice of professionals worldwide, the MPX K offers a closed bolt gas piston system that is ultra-reliable and durable. As with all MPX, the K is modular allowing for multiple handguard and barrel lengths and is ready to go for suppressor use. The K also features an updated M-Lok handguard which is available as accessories in multiple lengths for suppressor coverage. Finally, the K is upgraded with the ultra-smooth, ultra-fast Timney Trigger. Co-designed by Timney and SIG, this trigger offers the Timney performance you have come to expect with the ultimate reliability to make it survive the punishment of a sub gun platform. If you are looking for the ultimate modular sub gun, look no further than the MPX K from SIG SAUER.
