There are a few different heights available from different manufacturers. Probably what doc's "ish" was.

no, my ish was measuring from the top ID of the barrel hole to the top of the rail, then the barrel hole divided by half and added to it.

on 5 different "normal" flat top uppers :laughing:

I have one that is a high rise and another that is a mid rise which I believe is fairly standard. High rise of course to help clear larger objective optics.

I seen one at a gun show that was frickin' enormous! Must have been a full 3/4" higher than "standard."
