Just got done building my first AR. Don't know why so many say buy your first, because it went together with only small hitches (takedown and pivot pin springs were too long, had to cut a few coils off, after accidentally shooting the pin across the room and under a desk.)
Ok, I have a few questions though. First, is there anything else I need to do (other than shoot it?) I've done a functions check and everything does what it should, and I CLPd pretty much everything that moved.
Second, I don't have a stock wrench for the M4 type stock on my rifle. Is there some alternative way to tighten up the nut? I'd just go at it with a punch, but I don't want to mess it up.
Finally, the rear takedown pin seems extremely tight (had to tap it with a hammer to get it into place with the upper installed.) I clipped off a couple loops of the retaining pin spring and this helped, but I'm afraid of cutting it too short. Does it just need to 'wear in' a bit, or should I cut the spring some more?
Thanks,
J
