Looked at one the other day and I'm a dedicated Remington fan. It's a slight improvement over the 710, but still a cheap rifle. Bolt is a little smoother, but still crudely made. As someone who owns and has shot thousands of rounds thru Rem 700's, I cannot appreciate the 770. It does nothing for me. An old milsurp sporterized Mauser does more for me than the 770.
For an extra $100 or so you can get the SPS.
