The Trijicon ACOG 3.5x35LED .223 Red Chevron is a rugged, battle-ready riflescope built from forged 7075-T6 aircraft-aluminum that delivers nearly indestructible reliability for demanding field use, with a user-selectable LED illumination system offering six brightness levels (with an off setting between each) to tailor reticle illumination in transitional lighting, powered by a single AA battery that yields over 12,000 continuous hours on setting number four. This 3.5x optic features a red chevron reticle calibrated for .223, Bullet Drop Compensator options, and Bindon Aiming Concept compatibility, allowing rapid target acquisition across varying distances, while fully night vision device compatible operation expands its utility in low-light environments. The LED ACOG integrates seamlessly with most 3.5x35 ACOG accessories and ships with the TA51 thumb screw flattop adapter, battery, lens pen, lanyard assemblies, Trijicon logo sticker, manual, and warranty card, ensuring immediate deployment and ongoing maintenance. With a compact 8.0 inch length, 2.4 inch eye relief, 0.39 inch exit pupil, and a 28.9-foot field of view at 100 yards, this sighting system provides precise elevation and windage adjustments, robust durability, and versatile reticle options for precision shooting, patrol engagements, and dynamic tactical scenarios.
