we make the ring mount for this set-up (the part that attaches the scope to periscope.)
the ring is also used in microscopes and telescopes.
we also did some for the iphone that can be used on the same setup.
The ones for the iphone are not on the market yet. SWATSCOPE.COM
We don't make this one but this is the jist of using the iphone with night vision. this one is really expensive. iPhone 4,4S AN/PVS-14 Night Vision Adapter
