Used one night $4400 or best reasonable offer.
PVS-14 adaptor is installed (with no damage to the unit) a necessary upgrade.
Since I have a optics 1 ecoti coming from TNVC I will not be needing this.
The original eye piece has a small eye box, and small aperture opening. The 14-Upgrade makes the unit more forgiving to the eye (A must for helmet mount) and it also has the added benefit of working with a number of standard attachments designed for the 14. (Camera, filters, ect...)
