I have a PSA103, with a folding stock. Love the gun, however I have experienced a problem. Problem is that sometimes pieces of primer jams the firing pin. It has done this 3x out of 2300ish rounds. The ammo I was using was, Tula, Wolf, and Red Army. I have cleaned and disassembled the bolt and haven't seen any glaring problems. Is there anything to look for or replace to make sure this doesn't happen, i.e. firing pin, bolt?
Thanks
