Trijicon ACOG 1.5x16S Compact Scope with Low Red 2 MOA Reticle

The Trijicon ACOG 1.5x16S compact scope is a fixed-magnification riflescope built for shooters who need speed and situational awareness without sacrificing optical quality. Purpose-designed for close-quarters work, tactical applications, and fast-paced competition, this 5.1-ounce optic delivers the combat-proven reliability Trijicon ACOGs are known for—more battlefield service hours than any other magnified sight—in a package light and slim enough for modern patrol rifles, short-barreled carbines, and fast-handling setups where every ounce counts.

The 1.5x magnification and 7.4-degree field of view make target acquisition instinctive; you're not hunting through a tube, you're looking at the world and pointing. The Low Red 2 MOA reticle cuts through clutter without overwhelming your vision. What truly sets the ACOG apart is dual-source illumination: fiber optics automatically adjust brightness to ambient light, and tritium provides a glow when the sun goes down—no batteries, no dead switches. The forged 7075-T6 aluminum body is aircraft-grade rugged, finished in matte black, and needs no tools to adjust windage and elevation; external adjusters with lanyards keep caps from vanishing in the field. Pair it with the included Trijicon Compact Mount featuring Q-LOC technology, and you get tool-free, one-handed installation on any Mil-Spec or NATO rail, plus a spring-loaded design that holds zero even if the knobs work loose.

Made in the USA, this is a scope that works hard and asks nothing in return—no batteries, no fussing, just point and shoot in any light.

Frequently Asked Questions

What rifles and rails is the ACOG 1.5x16S compatible with?

The scope mounts via the included Trijicon Compact Q-LOC mount, which is compatible with any Mil-Spec or NATO Picatinny rail. It has been fielded on M16, M4, and modern carbines, and works with any platform using standard Picatinny rails.

Will this scope work in darkness without a battery?

Yes. The dual-source illumination uses tritium, which glows passively in low-light conditions without batteries. The fiber optic system requires ambient light and won't generate reticle brightness in complete darkness, but the tritium phosphor will provide a visible glow.

How much does the scope weigh, and is it suitable for lightweight builds?

The scope alone weighs 5.1 ounces; with the included Q-LOC mount, the total is 6.8 ounces. This makes it one of the lightest magnified optics available, ideal for fast-handling carbines, SBRs, and builds where weight matters.

What's included in the box?

The package includes the ACOG 1.5x16S scope and the Trijicon Compact Q-LOC mount. Adjuster caps come with lanyard assemblies to prevent loss in the field.
