Midwest Industries AK Picatinny End Plate Adapter Features The Midwest Industries AK Picatinny End Plate Adapter replaces the rifle s standard factory trunnion with a Mil-Spec 1913 Picatinny rail giving AKM pattern rifles a modern mounting interface for the stock. Built specifically for the 4.5mm pin diameter found on many AK factory folders the adapter is matched precisely to that trunnion size to ensure correct fitment. Once installed it allows the use of 1913-style fixed or side folding stocks opening up a wide range of aftermarket stock options that would otherwise be incompatible. Steel tension blocks built into the design help the adapter maintain a snug rattle-free fit even under the recoil impulse of repeated firing. A 6061 hardcoat anodized aluminum body gives the adapter the strength to handle AK-pattern recoil forces reliably over the long term while keeping added weight to a minimum. Installation requires cutting off the stock tang and may call for some additional gunsmithing depending on the specific rifle so proper tools and care are recommended during the swap. Made 100% in the USA Midwest Industries backs this adapter with a lifetime warranty reflecting confidence in its long-term durability. For AK owners who want to modernize their stock setup with a true Picatinny interface this adapter is the foundation that makes it possible.
