The Hi-Lux TD-3C is an open reflex sight intended for optics ready pistol slides and other weapon systems for quick target acquisition. The reinforced electronic housing can withstand even the heaviest recoiling calibers. Machined from 7075-T6 Aluminum, the lightweight yet durable TD-3C red dot will make any weapon system more accurate. Precise adjustments move the point of aim 1 MOA per click for windage and elevation adjustments. With a 50,000 hour battery life at medium brightness (single dot), the TD-3C should last several years on a single battery. The lowest 2 brightness settings are Night Vision Compatible. The TD-3C utilizes a circle dot RCLED pattern. The circle subtends 34MOA (10 mils) and the center dot subtends 2.5 MOA (0.73 mils). The user will be able to cycle through the different reticle combinations. The TD-3C also has a motion sensor. After 3 minutes of inactivity or no motion, the TD-3C will enter sleep mode. Upon detecting movement, the TD-3C will turn on. After 4 hours of inactivity, the sight will power off completely to conserve battery. The TD-3C shares the same mounting footprint as the RMR.
