Has anyone tried a quality set of detachable rings? I would like to shoot all of my match rifles,but I don't want to buy Nightforce scopes for all of them.I have 6mm BR,.308,.300 RUM AI,and am going to build a 6.5x.284.Who make the best detachable rings.I have leupold Mark 4 rings on the .300 and Burris Signature on the others.
