Does anyone have any information on this rifle? rate of twist ect. I purchased it new in 1999 and still have the box and paperwork but it does not give specifics. I recently decided to sell/ trade it but keep getting questions like rate of twist and does it have a 5R barrel. It shots sub 1/4" groups at 100 with factory Fed Gold Match. I looked on the Rem website but cant find it in 308 WIN. Any information would be appreciated.
