I went out and shot my m4 for the first time. Very nice. I do have one question though. Is there a break in period to get her loosened up enough for some speed shooting? When pulling the trigger as fast as I could about every three shells the bolt would go to the rear to reload.
is this normal. I've only put 42 loads thru it to date. Afterwards, I broke it down, cleaned, and oiled. I'm going to try again tomorrow.
i should mention I didn't oil it when I assembled it, the bolt seemed already well oiled
