Accuracy with an AKM using COMBLOC surplus ammo is not great to begin with.:joyous:Chrome is for: ease of cleanup, corrosive ammo, and it does effect accuracy. From what I have read a non-chrome lined barrel is more accurate. I never heard of chrome lining upping the reliability of cycling east block ammo, its the barrel that's chromed not the feed ramp from what I understand.
I prefer the chrome lining, my Mosin's have it as well. Accuracy? If I can hit a man in the torso at 50 yards, both the rifle and myself have done our jobs.
