whitey,
I understand,and you may even be right.Can you tell from the bases how deep to cut the dovetail? Can you tell before you buy the mounts if the dovetail will pierce the reciever ring?Is there a "sattle"(sp)that solderes to the reciever ring to avoid piercing it?Is the maker of the mounts known,to buy a new "foot" for the rear ring,to allow fitting for elevation( to allow avoiding piercing the reciever ring).
