Trijicon ACOG 1.5x16S Compact Rifle Scope with .223 Reticle

The Trijicon ACOG 1.5x16S compact rifle scope is a legendary fixed-magnification optic built for shooters who need speed and reliability without sacrificing precision. This is the scope that set the standard for tactical rifles, AR-platform rifles, and close-quarters work—trusted by military and law enforcement worldwide for good reason. At just 5.1 ounces and engineered in forged 7075-T6 aircraft-grade aluminum, it's compact enough for CQB and competition yet robust enough to handle whatever conditions you throw at it.

What makes the ACOG 1.5x16S stand out is its dual-illumination system. Fiber optics automatically harvest ambient light to keep your reticle visible and properly contrasted throughout the day, while tritium provides a glow in low-light and night conditions—no batteries required. The .223 Rapid Target (RTR) reticle with bullet-drop compensation is calibrated for 55-grain ammunition and features the Bindon Aiming Concept (BAC), which lets you shoot accurately at distance without doing math in your head. The larger 7.4-degree field of view makes target acquisition fast, and the 1.5x magnification keeps your eye box forgiving—ideal if you're moving, transitioning, or working in close quarters.

The Trijicon Q-LOC mount included with this scope uses a spring-loaded, one-handed tool-free system and is compatible with any Mil-Spec or NATO Picatinny rail. External windage and elevation adjusters mean no gunsmithing required; caps are tethered so you won't lose them in the field. Made in the USA with a matte-black anodized finish, this is gear that works when it matters.

Frequently Asked Questions

What rails does the ACOG 1.5x16S mount to?

The included Trijicon Q-LOC Compact Mount is compatible with any Mil-Spec or NATO Picatinny rail, including standard AR-15 upper receivers and similar platforms.

How does the illumination work without batteries?

The ACOG uses two battery-free light sources: a fiber-optic element that automatically adjusts to ambient daylight, and a tritium lamp that glows in low-light and night conditions. You never need to replace batteries or manage power.

Is this scope suitable for .223 / 5.56 rifles?

Yes. This model is calibrated specifically for .223 Rem with 55-grain ammunition, with a bullet-drop-compensating reticle and Bindon Aiming Concept built for that cartridge.

What's the field of view, and is 1.5x magnification good for close-range shooting?

The 7.4-degree field of view (39 feet at 100 yards) is wide for a magnified scope, making it ideal for close quarters and fast-moving targets. The 1.5x magnification keeps your eye relief generous and your eye box forgiving during rapid transitions and movement.
