I've been shooting ARs for awhile, mostly scoped, with plain ole trigger, and Mil surplus ammo. I bit the bullet, and got a Bushy A2 match upper. A couple of other firemen, and myself, decided to shoot in the S.E. Police and Fire games this year. The only requirements I know of, are the gun has to be military style, with iron sights. We will be shooting 100yds, standing, at black silhouettes(?spelling). Questions: What moa is this rifle capable of? Should I invest in a trigger upgrade? What is a normal good score? Are crosshair front sights legal in most competitions? How do most matches score? What ammo should I shoot? I don't reload, and don't have a fortune to spend. I'm a member of a range that is about 5 min from my house, I practice at least once a week. I shoot fair, but really want to improve. I have read and read all the topics I can find on arfcom, and they have helped a lot. I want to get better. I know this rifle can out shoot my current abilities. How do I get closer to shooting what it is capable of? Please help a fellow ARFCOMER get better, Any advice will be greatly appreciated. Thanks, Treeman
