Was excited to use this to extend the abilities of my Yukon SeaWolf NVMT monocular into a night rifle scope. However, when mounted, the eyecup is too far forward for easy viewing when shouldering a rifle and aiming it. OH, and the biggest problem is HOW CAN YOU AIM IT? It has a lasersight attachment, but no way of adjusting it so that you can put lead on-target. Really serves as a way to use a rifle to look through a night monocular and NOT as a scope.
I hope that the package I received from Optics Planet/Yukon had missing items and this is easily an easily correctable oversight. If not, then don't waste your $, buy a dedicated night-vision riflescope, not a conversion kit.
Pros: Well-made to allow monocular to adapt to Weaver-style mounts on rifles
Cons: No assembly instructions, no apparent way to aim lasersight for targeting
