Last weekend I did my first competition at Piedmont Handgunners Association in NC. Is 321 a good or bad score? I was using a factory Bushmaster XM15-E2S, it has a 14 inch barrel and an izzy flash suppressor. Oh, and I sighted it in during the match Luckily the rangemaster had a wrench for the A2 front sight post. It was a blast! I met some good guys, who were all helpful and pretty good shots.
