Rail-mount tactical face shield system designed to fit CAG ACH and RCH combat helmets with side rail systems (compatible with the CAG ACH Rail System). Aluminum arms that extend the shield outward assist in cheeking a long gun and allows for excellent ventilation. Premium shield coatings feature an anti-abrasion hard coating on the exterior & permanent anti-fog on the interior. Optically correct lens. V-50 rating for fragmentation. Integral rubber seal at shield-helmet interface prevents liquid pass-through. Shield length of 6" allows for gas mask clearance. NOTE: Shield will NOT fit helmets with night vision goggle (NVG) mounts. Shield is designed for helmets without NVG mount.
