Midwest Industries HK MP5K End Plate Adaptor Features The Midwest Industries End Plate Adaptor adds a 1913 Picatinny interface to the back of an MP5K style receiver opening the door to side folding stocks and pistol braces that would otherwise be incompatible with the platform. Machined from hard coat anodized 6061 aluminum the adaptor is built to hold up to repeated folding and mounting cycles without loosening or wearing out. An anti-rotation QD sling swivel socket is integrated directly into the design giving shooters a secure quick detach sling mounting point without a separate part. Installation is simple though some fitting may be required due to variation between MP5K clones and genuine HK SP5 receivers. This adaptor is compatible with the HK MP5K as well as widely used clone platforms including the Century AP5K Zenith ZF5K and Military Arms Corporation MAC 5K. At an installed weight of roughly 3 ounces it adds minimal bulk while unlocking a far wider range of stock and brace options. The part is made in the USA and 922r compliant an important consideration for imported MP5 clone builds. For owners of MP5K platform firearms looking to add a folding stock or brace the Midwest Industries End Plate Adaptor is a purpose built solution backed by a lifetime warranty.
