I owned one of those IORs you have. I thought the glass was nice but couldn't stand the short eye-relief.
This was probably two years ago, they may have corrected that problem.
I have had good luck with the A.R.M.S. # 22's QD rings w/spacers. You can find them used with 1" reducers under 90.00 (on ARfcoms EE) now and then. You just have to figure which height you need, probably High....
Good luck and post pics when you get a chance
