Midwest Industries HK MP5K Top Rail M-LOK Features The Midwest Industries HK MP5K Top Rail is designed to fit 9mm MP5K and SP89 receivers giving shooters a modern Picatinny mounting surface without permanently altering the factory handguard. The rail allows a user to mount an optic along with a light or laser at the same time something the factory configuration does not easily support. A forward M-LOK slot adds further mounting flexibility for accessories beyond the top rail itself. Installation requires no gunsmithing and Midwest Industries includes all the tools needed to complete the job at home. Machined from 6061 aluminum and finished with a hard coat anodized black coating the rail is built to hold up to a lifetime of service in the field or at the range. At just 3.9 ounces the added weight is negligible on a compact MP5K build. The rail is 100 percent made in the USA and 922r compliant an important consideration for imported MP5 clone builds. Backed by a Midwest Industries lifetime warranty this top rail is a dependable upgrade for MP5K owners for sale at GrabAGun.
