Accurate and dependable will depend on your definition. If your AR does not feed and go bang dependably with either factory ammo or good handloads, it needs to go back to the manufacturer until it does.
AR's by design are accurate, as long as the barrel is decent. Benchrest accuracy will always be a crap shoot with any production rifle.
The dipped camo coating on the Remington tends to peel and flake and look nasty.
I'd buy the RRA, but it's your call.
