Lots of PM's about how to mount the Photon so thought I would do an update...
The device has a standard 30mm tube, so effectively a normal 30mm HIGH ring mount which would accomodate a 50mm optic or larger would suffice.
We have used a weaver accessory rail, with weaver ring mounts, simply as we have lots of these for demo stocks, and it was an easy solution.
Also our tactical solutions which you would use for airsoft or for tactical weaver/picatinny tails on sporting rifles could utilize the same system.
Hope this helps.
