The zoom ring on my DMS-1 ranges from 9 o'clock position turning clockwise to the 4:30ish position; it doesn't go to 6 so I don't think that will be an issue
You may want to reverify that, as I have my one year old DMS-1 sitting in front of me as I type this.
My DMS-1 zoom control turns counterclockwise as viewed from the firing position when transitioning from 1x (as depicted in the picture), to 4x.
The raised part of the zoom control must clear the top of the GG&G rail, which it doesn't.
My rings are the same height as the ones you reference, the only difference is the QR levers, so if your LaRue rail is placed as far back as this GG&G, it won't work.
OTOH. you may be able to mount the optic far enough to the rear where the ring does not interfere with the mount, where it clears the rear of the rail, but that may not be a usable setup, as the optic might be too far to the rear. I would have to see the mount on the rifle to know for sure.
