I'll chime in on this..
As the other guys have mentioned, moa scopes are "best" suited for the rangefinder no question, however, if a guy (has) a MIL scope and wants to utilize the rangefinder with it... what you can do is put together your drop-data and have a BDC (yardage) turret-wrap made up by the custom-turret-system guys, then set the G7 for BDC mode. Works perfect. In BDC mode, MIL is irrelevant (minus the windage feature obviously) ...the only way around that to a certain degree is to add the windage (in MIL's) onto your turret-wrap and simply go by that for holdover after making whatever-said wind call is neccessary
Far as ranging-itself goes though, in BDC mode, the G7 works just fine for MIL scopes too
Just figured I'd mention this as a "for what it's worth" point to think about** Person doesn't have-to switch every-optic on his rifles to match as an MOA based scope, to be able to use the ranging (and range correction) capability of the G7
