I have 2 R15s one rifle 22" barrel and a carbine 18" barrel with the adjustable butt stock. They both shoot under an inch with most loads I've shot.I use 50 gr Ballistic tips and VVN133. Kills coyotes.I like the carbine with the short barrel and the stock can be set where you want it for the position you're in while calling. I've had good luck with different brand ARs too,you can get junk from any of the makers. Do all the different makers, make their own uppers and lowers? No! The parts are basicly all the same (except for aftermarket triggers and barrels) Yes you can nit pick if you want. I know everyone has one that will shoot 1/4 inch all day long but, I have yet to see one at any benchrest matches.
Get what makes you happy and enjoy it.
