Man, that is ugly.
I went with low 30mm on EGW rail, mediums were a bit too high.
Which brand for medium rings? I only ask because there is a lot of variation. I find for most 1.18” mediums are perfect while 1.26” mediums are good for TRG/AI AW/AE but slightly too high for most combinations. I will likely be going with an EGW rail as well.
Leupold Open Range, medium.99 were a tad too high for my 4-20x50, the low .89 were right on.
