OpticGard Holosun 507C-X3/407C-X3 Scope Cover FDE One Size. The intelligent cut allows the cover to fit most rear and suppressor sights. It also includes a detachable training lens which will allow you to use the red dot even in the sun or bright areas. Scope covers are made from a material made from TPU (Thermoplastic Polyurethane) offering protection from abrasion. In addition the fast and simple installation allows easy access to the buttons without removing the cover. Finally the interlocking pins secures the cover so it won't fall off even with heavy recoil from handgun slides. Are you tired of taping your optic for occlusion training? Removable training lens is the modern solution Note: Important Information OpticGard Covers may not be compatible with backup sights that are mounted in front of the optic. Sufficient space is needed for the cover to latch onto the front of the optic housing. OpticGard will add approximately 0.08 inches (2mm) to the sides of the optic. If using in conjunction with a holster please make sure there is sufficient spacing between the holster with the cover on.
