The Trijicon ACOG TA45 1.5x24mm compact rifle scope is a lightweight, battery-free optic purpose-built for shooters who need fast target acquisition, wide field of view, and reliable performance in any lighting condition. Built on Trijicon's legendary ACOG platform, this 1.5x magnification scope combines fiber-optic and tritium illumination to keep your reticle visible from low-light hunting situations to bright midday range sessions—no batteries to drain or replace. The generous 1.5x power and large exit pupil give you natural eye relief and forgiving eye box, making it equally at home on a defensive rifle, hunting platform, or range gun.
The dual-illuminated reticle uses Trijicon's Bindon Aiming Concept (BAC) design, which means the red reticle is optimized for speed and instinctive shooting. A wide field of view—25.6 feet at 100 yards—keeps target and environment in frame, crucial when threat or target displacement matters. The 24mm objective gathers plenty of light without adding bulk or weight that slows handling.
Mounting is handled by Trijicon's Q-LOC system: a forged 6061-T6 aluminum mount with one-handed, tool-free installation and a spring-loaded design that locks and returns to zero reliably, even if you don't cinch the knobs down completely. The mount seats securely on any Mil-Spec or NATO Picatinny rail and is rated for drop testing. At 8.4 ounces total (scope and mount), this ACOG stays light enough for all-day carry without sacrificing durability or optical clarity. Made in the USA with a matte black anodized finish.

Yes. The Q-LOC mount is designed for any Mil-Spec or NATO Picatinny rail, so it'll work on AR-15s, AR-10s, and any rifle with a standard rail interface. Installation is tool-free and one-handed.
No. The dual-illuminated reticle is powered by fiber optics during the day and tritium at night, so there are no batteries to buy, install, or worry about dying at a critical moment.
The 1.5x magnification keeps your field of view wide and your eye box forgiving, making it ideal for close-to-mid-range shooting, home defense, or hunting in brush where speed matters more than distance. The lower power also means less weight and a longer eye relief—you don't need to mount it as close to your face. If you're shooting past 300 yards regularly, a higher-power scope may be better.
Yes. The Trijicon Q-LOC Technology Mount comes with the scope and is ready to attach to your rifle's Picatinny rail.
