I tell everyone in the AR market that it is hard to go wrong with getting the ABCD's when it comes to ARs: Armalite, Bushmaster, Colt, DPMS.
I have one each Armalite and DPMS. I love 'em both. In the recent hurricanes in FL, the DPMS was my constant companion, but only because it had the 16" barrel. Either was perfectly serviceable and reliable.
