Good product, very versatile - Armasight by Rayvn Group Modular Bridge Mount, Rail System w/2 Pods

I had looked at a few devices along these lines. I chose this one because of the versatility in that I could run a, helmet mounted, co witnessed night vision monocular (in this case a PVS-14) with a thermal monocular. It isn't true fusion but it is a lot less expensive and opens up more then just the standalone NV. I mounted a ATN ODIN LT as well and so far have been pleased. I find a significant selling point is that you can swap things in the field, with an extra pod, so you could run two night vision units while driving to a location then swap to NV/thermal in under a minute to watch the area, or just slid off the second unit, until you need it, to run just a monocular. The mount is very intuitive so if you need to adjust something it is pretty straightforward, with a good range of adjustment. I haven't been able to work with the unit as much as I like before writing a review, but at this time I'd say it is worth the price.
