Trijicon 100154 ACOG 3.5x35mm Illuminated Red Horseshoe .308/7.62 BDC Riflescope - Black Hardcoat Anodized

The Trijicon ACOG (Advanced Combat Optical Gunsight) is a fixed-power, battle-proven riflescope calibrated for .308 Winchester and 7.62x51mm NATO rifles. This 3.5x35mm configuration (model TA11H308, MPN 100154) pairs a 3.5x fixed magnification with a 35mm objective lens and the iconic illuminated red horseshoe .308/7.62 BDC reticle for rapid, intuitive holdovers at extended ranges.

The ACOG is engineered for hard use in the field. A rugged aluminum housing is finished in black hardcoat anodized for corrosion and abrasion resistance, while multi-coated lenses maximize light transmission and target contrast. The sealed tube is fogproof, waterproof, and shockproof, and the optic is calibrated at 3 clicks per inch at 100 yards for precise, repeatable zeroing.

This model uses Trijicon's dual-illumination reticle system, which keeps the horseshoe and BDC stadia lit in both daylight and low-light conditions without the need for batteries. With 2.39" of eye relief, an 8" overall length, a 14 oz weight, and a 28.90 ft field of view at 100 yards, the 3.5x35 ACOG is a purpose-built .308/7.62 BDC combat optic ready for any .308 / 7.62 NATO rifle platform.
