Congrats! Love my MAADI!
My CAI Maadi MISR-10 SA does 3-4 MOA with iron sights and my 67 year old eyes using white box Ulyanovsk 8M3.
Sources for AKM parts and furniture are APEX, RTG, and Desert Fox sales. If you want to refinish it totally, strip the paint os with JASCO or Citri-strip, wash and rinse in hot, soapy water, the clear hot water and let dry in the sun. I would use Rustoleum High Temp semi-gloss black paint. Use about 4-5 THIN coats, allowing to dry in between. This is the system I used refinisjing Saigas that I "restored" to military spec.
