A friend of mine who is a rifle builder of some renown is rebarreling an old Rem 700 action for me (300WBY mag) and I'm going to mount an ATACR 5-25x56 but I've been wanting to drop the pic base for some reason. I fell in like with the NF direct mount before I saw that it doesn't come in 34mm for some dumb reason. Looking around I found the Hawkins "long range hybrid rings". Does anyone have any experience using these -- or any Hawkins rings?
