Trijicon 100145 ACOG 3.5x35mm Illuminated Red Chevron .223/5.56 BDC Riflescope - Matte Black

The Trijicon ACOG (model TA11F, part number 100145) is a combat-proven 3.5x35mm fixed-magnification riflescope purpose-built for .223/5.56 flat-top rifles. This configuration features a matte black hardcoat-anodized finish and an illuminated red chevron .223/5.56 BDC reticle calibrated for bullet drop compensation out to 800 meters.

The ACOG (Advanced Combat Optical Gunsight) has been a staple of military and law enforcement long-gun setups for decades, delivering fast target acquisition and enhanced hit probability for AR-15 and M16-pattern rifles. A 3.5x magnification paired with a 35mm objective yields a generous 5.5 degree field of view and a comfortable 2.39" eye relief. The fully multi-coated lens system maximizes light transmission and clarity across the sight picture.

Built for hard use in the field, this ACOG is fogproof, waterproof, and shock-resistant. The illuminated red chevron reticle is powered by Trijicon's fiber-optic and tritium system, delivering battery-free aiming illumination across lighting conditions. The chevron aiming point allows precise holdover through the .223/5.56 BDC ladder.

This factory-new Trijicon ACOG ships ready to mount and includes a flattop adapter for clamping directly to a Picatinny rail. Overall length is 8" with a weight of 14 oz.
