The ITT Shuttered Eye-Guard for 6015 or PVS-14 Night Vision Monocular is designed specifically for the PVS-14 and 6015 night vision monocular. This eyepiece was engineered to minimize the reflective glow from the NVD on the user's face, which provides a higher stealth factor. Remain unseen while observing your target with this eyepiece. This is an extreme peripheral accessory from ITT. It is a special order item only.
