Trijicon ACOG 4x32 Rifle Scope - Matte Finish, .223 Green Crosshair, Includes Picatinny Adapter

The Trijicon ACOG 4x32 rifle scope is a combat-proven optic that's been the choice of military and law enforcement for decades—and it translates directly to reliable hunting and range performance. This 4x32 model pairs a compact 32mm objective with a fixed 4-power magnification that excels at intermediate ranges without sacrificing field of view or light transmission. Built on Trijicon's legendary dual-illumination system, the reticle glows via both fiber optics during daylight and tritium for low-light conditions, so you've got a bright aiming point regardless of when you're shooting. The scope is calibrated for .223 ammunition and uses Trijicon's signature Bindon Aiming Concept—a ranging reticle designed to handle bullet drop compensation out to 600 meters without requiring manual turret adjustments, making it ideal for shooters who want speed and simplicity in the field.

Physically, the ACOG stays light and compact at 9.9 ounces and 5.8 inches long, making it an excellent fit for modern rifles where weight and balance matter. The forged aluminum housing is matte finished and built to survive hard use, while the green crosshair reticle offers excellent contrast across varied lighting and terrain. Eye relief sits at a comfortable 1.5 inches, and the 8mm exit pupil keeps things forgiving if your cheek weld isn't perfectly repeatable. This version comes with a TA51 Picatinny adapter mount already included, so you're ready to bolt it straight onto a flat-top AR or compatible platform without hunting for additional hardware.

Whether you're setting up a dedicated .223 rifle for hunting, running a three-gun course, or simply want a no-nonsense scope that performs across daylight and dusk, the ACOG 4x32 delivers the kind of rugged reliability that's made this design an industry standard. It's not a precision long-range scope—it's a workhorse that rewards users who understand its design and run it the way it was intended.

Frequently Asked Questions

Does this scope come with a mount?

Yes. The ACOG 4x32 includes the TA51 Picatinny adapter mount, so you can install it directly on any flat-top rifle or handguard with Picatinny rails.

Is the ACOG 4x32 good for hunting with an AR-15 in .223?

The ACOG 4x32 is calibrated specifically for .223 and its ranging reticle works out to 600 meters, making it a practical choice for varmint hunting and target work with modern rifles. The fixed 4x magnification keeps the field of view broad and handling fast, which suits intermediate-range hunting where you're not pushing extreme distances.

How does the dual-illumination system work?

The reticle combines fiber optics, which collect ambient light during the day for a bright glow, and tritium, a self-illuminating isotope that glows in low light or darkness without needing batteries. This means your aiming point stays visible dawn through dusk and beyond, regardless of power.

What does the ranging reticle do?

The ACOG's ranging reticle is etched with holdover marks calibrated for .223 ammunition. These marks account for bullet drop at various distances up to 600 meters, allowing you to aim at different heights on the reticle to compensate for drop without turning turrets. This design prioritizes speed and simplicity in dynamic shooting environments.
