So I bought a used set of rings look brand new still in open box. Box even says med high .92" right? My question is where is this measured from cause I'm pretty damn sure these are med. Rings. Just eye balling them I have a set of lows and a set of med highs on rifles but it's hard to get a accurate measurement with them on the rifle. Anybody got a set laying around not mounted they can measure for me or tell me were the .92 comes from?
