The Midwest Industries HK MP5K M-LOK Aluminum Top Rail is a purpose-built mounting solution for MP5K owners and clone builders who want to add modern optics and tactical lighting without gunsmith work. This aluminum top rail replaces the factory setup, giving you genuine M-LOK slots for attaching red dots, magnified optics, flashlights, or lasers—all while keeping your original handguard in place. It's designed specifically for 9mm MP5K receivers; 40 cal and 10mm variants may experience fitment issues, so verify compatibility before ordering.
Installation is straightforward. Midwest Industries includes all the tools you need in the box, so you can have your rail mounted and ready for your first optic in an afternoon. The rock-solid design keeps your accessories zeroed and stable through shooting sessions, training, or duty use. Built from 6061 aluminum with hard-coat anodizing, this rail handles field conditions without degrading—it's engineered for a lifetime of service, backed by Midwest Industries' lifetime warranty.
Weighing just 3.9 ounces, the rail adds minimal bulk to your platform. Every unit is manufactured in the U.S.A. and complies with 922R regulations for those who care about American-made quality. Whether you're running a precision carbine build, a home-defense AR pistol clone, or a range toy, this M-LOK top rail gives you the flexibility to configure your MP5K exactly how you want it.
