Re: Can a 34mm AI Mount be bored out to 35mm for USO?
You would have to take about 0.0395" out of the scope rings. And do it perfectly evenly to prevent issues with alignment. Possible... yes, with a good lathe, face plate or four-jaw chuck. And you would probably need a pin hone.
If I were trying to do it... I would cut the rings one at a time on a lathe to remove about .035". Then mount and torque the rings next to each other in a base and use a pin hone to take the last .004" out of them as a matched pair.
Keep in mind that you will also be removing any coating and the raw metal underneath will be susceptable to corrosion/oxidation.
It's a lot of work.
Possible? Yes. But worth it... probably not. You would be better off getting some USO rings or similar high-end rings that are the right diameter to begin with.
Hope this helps and cheers,

Thanks for the very informative reply, it is appreciated!
I have the 35mm USO rings, but really wanted (but not absolutely needed) a single piece mount for quick removal/installation.
You are probably right though about it not being worth it.
