Re: can you interchange brands of turn in type rings and bases ?
You're talking about the original Redfield-type rings that had a rotating dovetail for the front and dual-side screw lock on the rear. Now Leupold, Burris, Millet, etc. all make them and, YES they are interchangeable - matter of fact, for esthetics, the best looking combination is Burris rings and the sculptured Leupold bases. If you're after anything particular let me know, I have lots of spare sets rings and bases for 700's and 70's. Not trying to sell anything but if you want to "try" some we can work something out. Save you having to buy something that you find out you doesn't work for you.
