Trijicon 3.5x35 LED Battery ACOG Rifle Scope - .308 Green Crosshair, Matte Finish w/ Picatinny Adapter

The Trijicon 3.5x35 LED Battery ACOG rifle scope brings proven combat-grade optics to hunters, precision shooters, and tactical users who demand rugged reliability in variable light. Built on the legendary ACOG platform, this .308-calibrated scope pairs a green crosshair reticle with user-adjustable LED illumination—a first for the ACOG line—letting you dial brightness to match dawn, dusk, or day shooting without sacrificing battery life. Powered by a single AA battery with over 12,000 hours of continuous runtime (on mid-range setting #4), this is a scope that works when you need it and doesn't demand constant battery babysitting.

The optic is machined from 7075-T6 aircraft aluminum and built to absorb the punishment of real-world use. Its 3.5x magnification and 35mm objective lens strike a practical balance for mid-range precision work—enough glass to resolve target detail without the bulk or weight of a true long-range system. The fixed 3.5x design means a simple, bombproof sight picture with no moving parts to fail in the field. Eye relief sits at 2.4 inches, giving you plenty of room behind the glass, and the scope is fully night vision device compatible if your mission calls for it.

The .308 reticle is calibrated for that cartridge and includes bullet drop compensation across a 40 MOA range of adjustment. Six selectable brightness levels, with an off position between each, let you dial in just enough illumination to see the crosshair without washing out your target in bright conditions. The TA51 Picatinny adapter (included) mounts directly to flat-top uppers or adapter rails, and Trijicon packages this scope with extras: an AA battery, lens pen, adjuster lanyard, and manual.
