Samson Rear Trunnion Stock Adapter Features The Samson Rear Trunnion Folding Stock Adapter is designed to fit most stamped AKM rifles that have a rear trunnion tang giving the rifle a standard 1913 Picatinny interface for mounting a folding stock. This all-metal construction is built from 6061-T6 aluminum a material chosen for its strength-to-weight ratio in firearm applications. The MIL-A-8625 Type III Class 2 anodized finish provides excellent corrosion and wear resistance holding up to repeated folding and use over time. Installation is designed to be easy letting AK owners convert their rifle s stock interface without extensive gunsmithing. Manufactured entirely in New Hampshire USA this adapter reflects Samson s commitment to domestic production and quality control. The Black anodized finish matches well with most AK platform finishes keeping the rifle s overall appearance consistent. Because the adapter does not include a firearm it is sold strictly as the mounting hardware needed for the conversion. AK owners looking to add Picatinny-compatible folding stock capability to a stamped AKM rifle will find this adapter a dependable made-in-USA solution.
