Things I liked: Top of the line quality - solid as the Rock of Gibralter! You get what you pay for.
Things I would have changed: Nothing ... but make sure you've got adequate room on your dovetail for them. I pretty much ran out of wiggle room on the forward end. A skinnier set of mounts would have allowed more eye relief.
What others should know: I'll just say this - I met with a master gunsmith and showed him my rig. One of the first things he commented on was the scope mounts. Not the $500 scope - the mounts! That says something!
