50 moa mount and 20x SWFA moa-quad on most of my guns. Dial from 25 to 500 yards with no holdover. Not really ELR but good enough to impress the occasional CF shooter.
I have a SWFA 3-15 on mine and with a 20 moa rail i come up a 0.5 mil short at 500. I could switch to a 30 moa base but I seldom shoot over 400 so that's not a issue for me.
