Trijicon 100502 ACOG 3.5x35mm LED Illuminated Green Crosshair 308/7.62 BDC Riflescope - Matte Black

The Trijicon 100502 ACOG 3.5x35 is a fixed-magnification combat riflescope purpose-built for .308 Winchester / 7.62 NATO service rifles. Part of Trijicon's Advanced Combat Optical Gunsight (ACOG) family, this LED-illuminated variant delivers the legendary durability that has made the ACOG a staple of military and law enforcement long-gun programs worldwide.

At the heart of the optic is a 3.5x magnification fixed-power optical system with a 35mm objective lens housed in a rugged 30mm-35mm tube. The scope features Trijicon's user-selectable LED illumination with six adjustable brightness settings (and an "off" position between each setting) powering an illuminated green crosshair reticle calibrated with a .308/7.62 BDC bullet-drop compensator. The reticle provides holdover points for common .308/7.62 engagements without requiring the shooter to manipulate turrets under fire.

Optical performance is anchored by multi-coated lenses with an anti-reflective coating that maximizes light transmission and image clarity. The scope provides a 28.90 ft @ 100 yds field of view and 2.40" of eye relief, with windage and elevation adjustments of 3 clicks per inch at 100 yards for precise zeroing. Overall length is 8" and weight is 16.80 oz.

The ACOG 3.5x35 LED is built around a matte black aluminum housing engineered for the harshest field conditions. It carries fog, shock, and water-resistant sealing so the optic continues to hold zero and function reliably through recoil, immersion, and temperature extremes. The fixed-magnification, battery-powered LED platform is designed to enhance accuracy on tactical and duty rifles chambered in .308/7.62, making it a go-to choice for designated marksmen, patrol rifle programs, and serious recreational shooters.
