Sig Sauer’s MPX Copperhead K delivers high performance, versatility, and modularity in a compact package. This PDW utilizes the proven closed bolt gas piston system which is known for its reliability as well as ruggedness, and features ambidextrous AR-style controls. Like all of the premium firearms in the MPX family, the MPX Copperhead K is highly modular, allowing the user to interchange handguards, different barrel lengths, and install multiple muzzle devices such as suppressors and brakes. The rear of the MPX Copperhead K also features a picatinny rail for installing a pistol brace, or can be outfitted with a stock to convert the weapon into a Short Barreled Rifle (NFA paperwork required). The MPX Copperhead K’s magazine well is flared, promoting faster reloads, and features a textured surface on the front for a handy gripping surface. Other features of the MPX Copperhead K include a full length picatinny rail for installing iron sights and optics, and ambidextrous controls accommodate both left and right handed shooters. In addition, the MPX Copperhead K is outfitted with a smooth, ultra-fast trigger that was designed between Sig Sauer and Timney to ensure quick shooting and ultimate reliability.
