I just installed a new recoil spring in my Bulgarian 5.45mm AKS-74U. I had been having feed issues and tried that as a remedy.
It's firing two rounds, with a bolt over base malfunction on the third. If I fire rapidly, I can sometimes get more shots off between malfunctions, but it always happens, regardless of magazine, ammo type or muzzle device I use.
What other factors am I missing here?
