Trijicon 100163 ACOG 3.5x35 .223/5.56 BDC Illuminated Green Crosshair Riflescope - Black Hardcoat Anodized

The Trijicon ACOG (Advanced Combat Optical Gunsight) model 100163 is a fixed-power, combat-proven riflescope in the 3.5x35 configuration, purpose-built around the AR-15 and M16 platform chambered in .223 Remington / 5.56 NATO. The ranging reticle is calibrated to 1000 meters for flat-top 5.56 rifles, giving operators rapid holdover out to extended distances without manipulating turrets, and the optic is designed for enhanced target identification and hit probability out to 600 meters.

At the optical heart of the scope sits a 35mm objective paired with 3.5x magnification, a 28.90 ft field of view at 100 yards, and a generous 2.4 inches of eye relief for fast, both-eyes-open target acquisition. The illuminated green crosshair .223/5.56 BDC reticle is dual-illuminated by tritium and fiber optics, so it runs battery-free in any lighting condition from bright sun to low/no light. Lenses are multi-coated for clarity and the housing is finished in black hardcoat anodized.

Built to Trijicon's combat-spec standard, this ACOG is fogproof, shockproof, and waterproof, with windage and elevation adjustment calibrated to 3 clicks per inch at 100 yards. Total length is 8 inches at a carry weight of 14 ounces, making it compact enough for a flat-top rifle while delivering the rugged durability the ACOG line is known for. The same platform is trusted by US military and law enforcement units worldwide.

What is included: a flattop adaptor for Military Style Rail and a Scopecoat. Made in the USA by Trijicon.
