The TA31RCO riflescope incorporates Trijicon's dual-illuminated red chevron-shaped reticle and bullet drop compensator. In low light or at night, the chevron is brightly illuminated by tritium; in daylight, a fiber optic system collects ambient light and helps ensure daytime brightness and controlled contrast. The system is totally battery-free. A new Target Reference System will allow a rifleman to quickly and accurately reference the location of a target and communicate that location to fellow Marines. The TA31RCO will also feature Trijicon's Bindon Aiming Concept , an optical breakthrough that permits a both-eyes-open shooting method that greatly increases hit ratios in fast moving Close Quarter Battle (CQB) scenarios.
