slobbergoat Posted August 16, 2022 Share Posted August 16, 2022 While cleaning my m4, I noticed that there seems to be a pair of stamped 'alignment marks' or something of that nature where the barrel is mated to the breach piece - they're not entirely aligned being off by about half a millimeter. Can post a photo if that's any help. Looking online, most removed barrel assemblies don't seem to have these marks at all. Is this anything to concern myself about? I spent a while staring at them but can't seem to see any noticeable misalignment with the front sight or so on that'd suggest that the barrel has been pressed on crooked.
