RMR: Adjustable vs. Non-adjustable Frame Thickness?

[jkrispies]

I'm curious if anybody out there owns both an adjustable model (RM01 and RM02) and non-adjustable model (RM06 and RM07) for the Trijicon RMR series red dots and can compare the two to tell me if the sidewalls on the non-adjustable window frames are visually (or measurably) any thinner between the two, beyond the additional thickness of the rubber buttons on the adjustable model?  Triji did a pretty good job of keeping those buttons low profile, but I'm wondering if the non-adjustable walls are even thinner due to no need for wiring, etc.  Thanks, John
