I am trying to stay on the cheap, but have the money to not buy a pile of crap either. Who makes good lowers, good uppers? I know OA, RR, Bushmaster, Colt, wondering if there is some good quality stuff with a minor price tag for the beginner? I'm mostly going to be using open sights for coyotes, small pigs, varmints, so I don't need match grade, 1000$ quality. BUT any cash I save means more shooters in the stable.
