Gary, I believe that a set of medium height rings would allow you enough clearance between the eye piece and hammer. As to brand, I lean towards Leupold, Burris, Warne or Talley. Others may feel differently. You've put out quite a lot already for the barrel and scope, why scrimp now. Whether you go with a Weaver style ring or dual dovetail, it's another matter of choice. The Weaver style may be easier to mount. With the dual dovetail rings, make sure that the rings are aligned properly. Whichever you go with will determine the type of mount.
