welcome, what part of ohio are you in? cleveland area here.
well here is my take on those rifles......they maybe good, but it really isn't worth spending that much money just for the name associated with them, which when you boil it down, that is what you're paying for.
are you going to be doing any serious competion shooting? if not, why spend a a small fortune for a AR,......RRA, BUSHMASTER, ARMALITE will do you just fine, and are quality rifles....COLT is also good, but you're going to paying more becasue of the name on it...those rifles, are no better or worse then the others I've mentioned, and don't warrant the higher price for them.
BTW RRA makes a legal DCM AR, if I was going to buy a competion AR, RRA is the one I would go with.
I own a EAGLE ARMS and a BUSHMASTER, and a RRA upper, and they are all great guns, and upper.....never a problem with any of them, and they are tack shooters.
just stay away from hesse, or vulcan arms, as they now call themselves, and ASA...... don't even think of buying one......garbage.
