Protect the covertness of your mission using the Tenebraex MRO Anti-Reflection Device with Flip-Up Cap from Trijicon. This honeycomb ADR (Anti-Reflection Device) significantly reduces reflections from your red dot sight's objective lens while maintaining your ability to make precision target acquisitions. The device can be easily attached to your standard MRO's objective lens by slipping it on the bezel. It also features a built-in flip-up lens cover to protect your optics from dust and dirt. For instant deployment when time matters, the lens cover has a built-in spring-loaded mechanism.
