Unconventional design, unmatched performance, and familiar AR handling. 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. 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.

KAC’s iconic Ribbed Rail Panels have seen use all over the globe on US military M4 Carbines. The lightweight polymer panels are ribbed for an enhanced grip, and help insulate the support hand from barrel heat. While originally designed for use on the KAC M4 RIS and M4 RAS rails, these panels are also compatible with many other railed handguards.

URX 4 The URX 4 is a continuous top-rail system that utilizes the Keymod mounting brackets developed by Vltor and Noveske. This rail system is built stronger and more stable than previous designs due to the absence of a removable bottom rail. The modular layout allows an end user to fully customize exactly where to place accessories without the use of specialized tools, small parts, or additional forces applied to the barrel.
The URX 4 is currently available for 5.56 rifles in 8.5, 10, 10.75″, 13, and 14.5 lengths, and is equipped with Knights unique IBN mounting configuration. The idea was to create a more modular, and thus more serviceable, rail system that still maintains its strength and stiffness. The IBN system torques the rail onto the weapon and allows the rail to act as the barrel nut. This design was developed to increase stabilization and provide a simpler solution that requires less specialized tools to install and maintain.
A full array of modular accessories, iron sights, and panel kits utilizing the Keymod mounting brackets have been developed specifically to accompany this rail system. With the introduction of the URX 4, Knights Armament Company demonstrates its continuing determination to intelligently design effective products.
Two QD sling swivel sockets built in at the rear of the rail. Includes shim kit and installation wrench.
