Fantastic pinnacle tube would have cost me the same by itself! - Armasight MNVD-51 1x19mm Night Vision Monocular

Great little unit. Uses the Mum rail system same as Armasights Sidekick 640 thermal. Tube is fantastic at 2000 FOM. The only thing as maybe a con is in order to get the 51 degree FOV your eyeball has to be right against the lens like a scanner. On my helmet even right against my glasses I won't get even the 40 degrees of my standard PVS 14. If it was the same money I in retrospect for helmet use would have prefered the 40 degree model with better eyebox. But since I'm still getting maybe 35 degrees on my helmet I'll live with it and have the plus of 51 degrees without my glasses on and handheld as a scanner.
