Midwest Industries AK Picatinny End Plate Adapter – Durable, Easy Installation

If you're running an AK and want to modernize your setup with tactical rails and compatible furniture, the Midwest Industries AK Picatinny End Plate Adapter is your bridge to Picatinny-rail-equipped stocks and accessories. This adapter replaces your standard trunnion with a true Mil-Spec 1913 rail, opening up options for fixed or side-folding stocks that would otherwise be incompatible with traditional AK rear tangs. Whether you shoot an AKM-pattern rifle, 4.5 pin configuration, 5.5 pin, or Yugo-platform gun, Midwest Industries makes a model for your platform—you just need to select the right one for your rifle.

The build quality reflects Midwest's reputation: the body is 6061 T6 aluminum with hardcoat anodizing for durability, and steel tension blocks ensure the adapter stays locked down tight to the receiver. Installation can be completed in roughly 15 minutes with the right tools, though you will need to remove or cut the existing stock tang as part of the process. Depending on your rifle's individual tolerances and condition, minor gunsmithing may be necessary, so budget a bit of extra time or have a gunsmith on speed dial if you're not comfortable with small modifications. Everything is manufactured in the USA, and Midwest backs it with a lifetime warranty.

This adapter is ideal for AK owners who want to run modern slings, cheek risers, optic mounting solutions, or any other gear designed around the Picatinny standard—all without replacing the rifle itself. It's a practical upgrade for hunters, tactical shooters, and anyone who values flexibility in their setup.
