We're going to try a YHM single slot offset rail with a ring and light. Probably one of the new Vltor rings. Pics will follow when the mount comes in. We already have rings and the light. I'd have preffered to use just 2 parts (the light and a offset ring) to the three (mount, ring and light), but the mount is pretty minimal. That's the one thing I'm looking forward to seeing. The YHM one slot only uses a single cross screw to tighten, and it looks a little on the skinny side. The next largest size, the 3 slot rail, is uses more screws, but is too large for what we need.
If it works out, and chances are it will work just fine, all is well. If not, maybe by the time we see a need to replace it, a better, lower profile offset ring will be out. Thanks to Brightflashlights for the suggestion and the mount!
