Keeping your MRO lenses clean and protected through active field use is one of those small habits that pays off when an opportunity presents itself and your optic is ready to go rather than covered in mud or rain. The Trijicon MRO Clear-Black Cover AC31021 wraps around the MRO with integral lens covers and a protective armor body that stays attached to the sight — nothing to lose in the field, nothing to fumble with when you need the optic ready fast. The design choice that makes the Trijicon MRO cover genuinely practical for field use is the integral lens cover system. The covers are built into the protective body — they open and close but they never detach, which means there is nothing to drop in the dirt, lose at the bottom of a pack, or leave behind at camp. For shooters and hunters who have dealt with lost lens covers at inconvenient moments, the integral design is immediately appreciated. The tactical scope wrap low-profile design allows the lens covers to be operated quickly with one hand without breaking your grip or your shooting position. The covers nest together under recoil, so they do not flop around or interfere with your sight picture when the rifle fires — a practical detail that makes the difference between a cover that works and one that creates its own set of problems during use. The scope cases AC31021 protective armor body shields the MRO housing from impacts, scratches, and the general abuse of hard field use without adding meaningful bulk to the overall sight package. Receptive to most spray paints and hydro dip processes for shooters who want to match the cover to a specific color scheme or camouflage pattern.
