By eyepiece do you mean reticle?
You may want to email Donkanab@pobox.com
and ask him.He has ben very helpful and cheaper than everyone else.
I also noticed they claim both the 30 and 35mm 6-24s focus down to 30yards but niether one of mine would at 24x,I also come up with more MOA adjustment than they do but mine is just a prototype?
If you dont want the illuminated reticle and want to save a little $ the 30mm will be easier to find rings for.
