I recently got my hands on some AKMS/AKM receiver blanks made by Radom. They are classified as blanks and are fully BAFTE compliant, no serial numbers, no paperwork required.
Compatible with all 1mm receiver parts kits, and cut for 7.62x39mm. Receiver requires trunion mounting, drilling/pinning, and heat treatment to complete assembly.
Make one yours and stay prepared! Only 0.5BTC or NMC/LTC equivalent!
Price includes shipping, cannot ship to CA, CO, CT, DC, MA, NJ, Chicago IL, New York NY, or outside the US. PM for a quote, at which point price will be locked in. Tracking and insurance additional. If you are hell bent on a 5.45mm receiver, shoot me a PM and we can work something out.
