I have to disagree.
I've seen some AR's that shoot better than any bolt gun I've ever seen -- comparing off the shelf to off the shelf -- 10 shot groups.
Rock River has several barrel contours now. Every RRA rifle I've owned or shot has been extremely accurate.
They make some lightweight rifles now, but the majority of their line is heavy.
Put a RRA Competition and a 700 Varmint on the bench side by side. Shoot a 10 shot group with quality ammo from each. I know where I'd put my money....
