I just purchased a Remington 700 SS Mil Spec in .308 that I will be shooting in tactical matches, ranges from 200 - 1000 yards, and in some prone matches with ranges from 300 - 1000 yards. I have a Leupold M1 3.5-10x40 LR scope in A.R.M.S 22 QR rings I will be using on it (I will also use the scope on the rifle it is currently on). What would you recommend for good scope bases to put on the rifle? Do you sell them? If not could you recommend a source? Thanks.
