Midwest Industries HK MP5K Picatinny Top Rail MLOK Black

The Midwest Industries HK MP5K Picatinny Top Rail with M-LOK in Black is a purpose-built optic mounting solution designed for the HK MP5K platform. This modular rail system enables operators to maintain factory handguard ergonomics while adding rails for sight systems and tactical accessories—a critical capability for users who rely on the MP5K's proven handling characteristics in close-quarters scenarios.

Constructed from 6061 aluminum with hard-coat anodizing, the rail delivers durability suitable for sustained duty use and training cycles. The forward M-LOK slot provides modularity for mounting lights, lasers, or supplementary accessories without permanent modification to the weapon. Installation requires no gunsmith services—all necessary tools are included—making this an accessible upgrade for both agency armorers and individual users. Midwest Industries backs the design with a lifetime warranty, reflecting confidence in material integrity and manufacturing precision.

This rail is engineered for tactical professionals, law enforcement operators, and specialized-duty personnel who require both optic-mounting capability and the retention of the MP5K's balanced handling package. The Picatinny standard ensures compatibility with industry-standard optics across red-dot and low-power scope platforms. Patent-pending design elements address the structural demands of modern duty and training loads, with 922R compliance confirmed for civilian ownership. Weighing 0.4 lbs and measuring 10 inches in length, the rail integrates seamlessly into the MP5K platform without shifting the weapon's balance point.
