Is in excellent condition.
I paid $575.00 with scope
Value of 257 Roberts Model 722 Serial No/ 319811
Value depends a lot on condition. S.P. Fjestad's current BLue Book of Gun Values places a Remington 722 in 90% condition at $300 + 20% for the .257 caliber = $360. Hope this helps, Shrigg
You will not likely find a Remington stock. I put my 722 in a Bell and Carlson stock and I love it.
Check the manufactured date link on the Remington Society of America for details.
