Midwest Industries HK MP5 Top Rail M-LOK Features The Midwest Industries HK MP5 Top Rail M-LOK is designed to fit 9mm HK MP5 and MP5A2 receivers giving the platform a modern mounting surface for red dots and magnified optics. The 0 MOA rail runs 10.38 inches long and 3 inches wide placing an optic at a usable height of 3.00 inches above the bore for a natural cheek weld. A forward facing M-LOK slot lets the shooter add a light or laser without giving up the optic mount keeping the handguard free of extra clamps. Installation uses the included mounting hardware and requires no gunsmithing so the rail goes on with simple hand tools. Constructed from 6061 aluminum and finished in a hard coat black anodized coating the rail is built to shrug off the wear of regular use while standing up to repeated mounting and removal. At just 4.60 ounces it adds minimal weight to the MP5 platform preserving the handling balance the gun is known for. Midwest Industries notes that fitment issues may occur on 40 caliber and 10mm variant receivers so the rail is matched specifically to the 9mm MP5 family. Backed by a lifetime warranty and made entirely in the United States the Midwest Industries HK MP5 Top Rail M-LOK is a straightforward upgrade for sale at GrabAGun for shooters modernizing their MP5 or clone.
