I also have 2 pairs of Redfield rings, 1 is the top screw and the other bottom screw. I measured the same way as I did the other 2 and found that the bottom screw is (measured from top to bottom) .080. The top screw is measured .083.
So I see that no mounts is actually 1" like they are suppose to be. Im sure that you could lap the rings for a better fit. I remember reading, I think that it was on here, that the USO mounts didnt have to be lapped but guess we could be wrong. </div></div>
Hmm, that's interesting. Are your Redfield rings new manufacture, or old stock?
The real Redfield rings, as well as the USO repro ones, seem pretty thin already and do not look like they have that much metal to give, either for lapping or whatever.
By the way, what would the height be for the Redfield rings used in the A1 mounts, medium or high? Dual dovetail or regular, or either with the bottom cut off and soldered on? And anybody know how the rings were attached to the bases in the original mounts? </div></div>
The ones that I have are old and come to think of it I think that the top screw ones are Leupold. I bought both of those about 3-4 years ago. The height for the rings on the M40a1 are medium. Im going to use the bottom screw mounts for my M40a1/Redfield build. I think there were a couple of different ways that they used to attach them to the base. One was to solder them to the base and I think the other way was to put a pin through the mounts to keep them in the same place.
In the DFA Vol 1 it shows some ways that they were attached. If it was a dovetail mount then underneath it would be bedded. The other mount would be soldered into place. There are pictures on page 67 and 70 that illustrate those 2 points. Ill go through all my books and see if I cant get a better pic for those points.
