Editor’s Note: The Sig MPX-K utilizes a 4.5-inch carbon steel barrel to help bring the already maneuverable MPX into an even lighter, handier package. Additionally, the MPX-K features a reliable and durable gas-piston system to help that helps reduce recoil and aids in suppression. The MPX also has fully ambidextrous AR-style controls, a Timney flat-face trigger, and boasts modularity that allows users to easily change handguards and barrel lengths.

By The Numbers
Accuracy
We had a great experience with the MPX and rang steel, no problem. That said, there are user reports that a suppressor can throw off your shots.
Reliability
We had one experience where a fully-loaded mag wouldn’t work with us…but that could be a mag issue. Outside of that instance, the gun worked great.
Customization
It’s an AR-style PCC…do what you will with it.
Ergonomics
The Sig MPX K adopts a familiar AR style that feels right at home if you love the AR platform.

FINAL VERDICT
"Despite some known issues that may require some attention, the Sig Sauer MPX is absolutely worth a look. The combination of familiar ergonomics in a sensibly laid-out package is a winning one in my book. And I think you’ll get what I mean if you manage to get your hands on one." - John Currie
