Trijicon 100153 ACOG 3.5x35mm .223/5.56 BDC Illuminated Red Horseshoe Riflescope - Black Hardcoat Anodized

The Trijicon ACOG (Advanced Combat Optical Gunsight) is a fixed-power, battle-proven riflescope trusted by U.S. military units, law enforcement, and tactical shooters worldwide. Model 100153 (TA11H) pairs 3.5x magnification with a 35mm objective lens, making it a purpose-built mid-range optic for the AR-15/M16 platform.

At the heart of this ACOG is the Illuminated Red Horseshoe .223/5.56 BDC reticle, calibrated for the ballistic profile of .223 Remington and 5.56 NATO ammunition. The horseshoe aiming point enables rapid target acquisition at close quarters, while the bullet drop compensator (BDC) hash marks allow the shooter to engage targets at extended ranges without manually dialing elevation. The reticle is dual illuminated by a combination of tritium and fiber-optic technology, providing a reliable aiming reference from bright daylight down to low/no-light conditions - no batteries required.

The scope carries a rugged black hardcoat anodized finish for corrosion resistance and reduced glare, with multi-coated optics that maximize light transmission and image clarity. A generous 2.40" eye relief and a wide 28.90 ft @ 100 yds field of view keep the shooter on target quickly, and the adjustment turrets click at 3 clicks per inch at 100 yards for precise, repeatable holds.

Engineered to Trijicon's legendary durability standards, the TA11H is fogproof, shockproof, and waterproof, built to survive the harshest field conditions. The optic measures 8" long and weighs 14 oz, offering a compact, lightweight footprint that complements service-rifle builds and 3-gun setups alike.
