No problem. I'm sorry I sold all of my one piece mounts about 5 months ago. I had a couple H&H magnum Redfields and Leupold mounts. There's not really a difference between the 2. Both good mounts, if that is what you desire. I personally like the 2 piece mounts, but you may have reasons for going with the 1 piece. Their biggest downfall is the windage adjustment screws. Don't gorilla torque those. I've bent them in the past!!!! If you don't need a 1 piece mount, I'd always suggest the 2 piece weavers or Leupold QWR's for an H&H receiver. They are strong and pretty sleek. They don't overhang the receiver, which I personally like. They are also steel and work great on H&H receivers. If you have 2 holes in the rear bridge:
Leupold QRW mounts:
Modified Weaver steel mounts:
