Trijicon 100175 ACOG 5.5x50mm Illuminated Red Chevron .308/7.62 BDC Riflescope - Black Hardcoat Anodized

The Trijicon 100175 ACOG is a fixed-magnification combat riflescope calibrated for .308 Winchester and 7.62x51mm NATO rifle platforms. Part of Trijicon's Advanced Combat Optical Gunsight line, this 100175 configuration pairs 5.5x magnification with a 50mm objective lens, delivering an 18.40 ft @ 100 yds field of view and a comfortable 2.20" eye relief for fast, intuitive target acquisition.

At its core, the ACOG features an illuminated red chevron .308/7.62 BDC reticle that provides calibrated bullet drop compensation out to extended ranges, while the bright center chevron offers a clean aiming reference for closer engagements. The illumination system keeps the reticle visible across varying lighting conditions without batteries. The optic offers parallax adjustment from 5 yards to infinity and precise 5 clicks per inch @ 100 yds windage and elevation adjustments for repeatable zero and reliable holdover corrections.

Built for hard use, the housing is finished in a black hardcoat anodized coating with multi-coated optics for excellent light transmission, and the unit is fully fogproof, shockproof, and waterproof. The 100175 measures 12 inches overall and weighs 25.60 oz.
