Midwest Industries AK Picatinny Adapter Converts AK Trunion to Picatinny Anodized Finish Black MI-AK-PEPA UPC 812102034292
Product Description
The Midwest Industries AK Picatinny Adapter (MI-AK-PEPA) is an indispensable stock conversion interface designed to adapt standard AK-47 and AK-74 fixed-stock rear receiver trunnions to accept modern MIL-STD-1913 Picatinny mounted stocks and folding mechanisms. Engineered for Kalashnikov modernization builds, this heavy-duty adapter plate enables operators to attach an infinite selection of folding buffer tubes, SIG-style folding stocks, and tactical braces without requiring permanent receiver modifications.
Precision CNC-machined in the USA from 6061-T6 billet aluminum and finished in a resilient Type III hardcoat anodized matte black, the MI-AK-PEPA mounts rock-solid into standard square-back AK stamped receivers. By converting the traditional rear tang layout into a vertical 1913 Picatinny rail section, it eliminates unwanted stock movement while providing full height adjustments for optimal cheek weld alignment with red dot sights and magnified optics.
Complete with high-strength mounting hardware, the Midwest Industries AK Picatinny Adapter delivers duty-grade stability, zero rotation under heavy recoil, and seamless modularity for hard-use custom AK platform builds.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Fits standard stamped-receiver AK-47 / AK-74 / AKM pattern rifles with single tang fixed-stock rear trunnions. Not compatible with milled receivers, Yugo/Zastava pattern rifles, or factory side-folding trunnions without adapter modifications.
- Perform a complete firearm safety check: drop the magazine, pull the charging handle rearward, and visually inspect the chamber to verify zero live rounds are present.
- Remove the top receiver dust cover, recoil spring assembly, bolt carrier group, and existing rear stock screws.
- Slide the factory buttstock out of the rear receiver socket.
- Insert the Midwest Industries MI-AK-PEPA adapter block into the rear receiver trunnion pocket, aligning the mounting holes with the receiver tang screw holes.
- Apply medium-strength threadlocker (Blue Loctite 242) to the included fasteners and torque firmly into place until the adapter sits completely flush against the rear receiver face.
- Attach your chosen 1913 Picatinny folding stock, brace, or buffer tube adapter onto the rear rail interface, clamping the rail bolt to 25–30 in-lbs.
