Mi Mp5K 1913 Edn Plate Adaptor Blk
If you're running an MP5K platform and want to mount a folding stock or brace, the Midwest Industries MP5K 1913 end plate adaptor is a straightforward solution. This aluminum adaptor uses the standard 1913 Picatinny interface—familiar to anyone who's worked with AR-pattern gear—to accept most side-folding stocks and braces designed for that mounting standard. It's engineered to fit the HK MP5K directly, and also works with popular clones including the Century AP5K, Zenith ZF5K, and Military Arms Corporation MAC 5K.
Built from hard coat anodized 6061 aluminum, the adaptor prioritizes durability without adding unnecessary weight to your platform. Installation is straightforward—no special tools or gunsmithing required—and the design includes an anti-rotation QD sling swivel socket, so you can mount a sling attachment without separate hardware. The whole setup is designed to be compact and reliable, fitting the MP5K's proven, no-nonsense ethos.
Whether you're setting up a home-defense carbine, a range gun, or a truck gun, this adaptor unlocks stock and brace options that can improve handling and control. It's a smart upgrade if your MP5K clone came without a rear support or if you want to change what you've got.
