Can't be an RLB as only the first 35 thou were so stamped and had the grasping groove stock. That said, if it has all Remington parts....no "buts" I wouldn't ask a dime under 1K with a nice bore and the documentation. I am still looking for a follower and buttplate marked cubby cover for my SN 3004295. Finding original Remingtons with no "buts" is real tough these days. Regards, Rick.
