Trijicon 4x32 ACOG Rifle Scope, .223 Green Crosshair, 3.25 MOA Red Dot RMR, Matte Finish

The Trijicon 4x32 ACOG rifle scope with integrated 3.25 MOA red dot RMR is a proven combat-to-civilian optic that pairs magnified shooting capability with a close-quarters backup sight. Built on the trusted Trijicon ACOG platform and calibrated for .223, this scope delivers the ranging precision and rapid target acquisition that hunters, tactical shooters, and precision riflemen have relied on for decades. The fiber-optic and tritium dual-illumination system keeps the green crosshair visible in bright daylight and low-light conditions without batteries, while the RMR Type 2 red dot on the upper rail gives you a point-and-shoot option for targets inside 100 yards.

The main scope uses Trijicon's Bindon Aiming Concept—a reticle design that allows you to dial bullet drop compensation out to 800 meters without manual turret adjustments, letting you focus on the shot instead of the math. The 4x magnification and 32mm objective lens strike a balance between light gathering and real-estate on your rail; it's not as bulky as a higher-power scope, but bright and capable enough for mid-range hunting and duty work. The forged aluminum housing is built to absorb recoil and rough handling, and the matte finish cuts glare without standing out in the field.

This package includes the TA51 flattop mount, the RMR already mounted and bore-sighted, a lens cleaning pen, adjustment cap lanyard, manual, and warranty card—everything you need to mount and run it. The 1.5-inch eye relief and 8mm exit pupil mean quick target acquisition and forgiving head position, which matters when you're moving or shooting from unconventional positions.

Frequently Asked Questions

Does the ACOG come mounted and ready to use?

Yes. The RMR Type 2 red dot is pre-installed on the upper rail and bore-sighted. The TA51 flattop mount is included, so you can attach the entire optic to an AR or any rifle with a Picatinny rail. You'll want to confirm zero at your range, but it ships ready to mount and shoot.

What makes the dual-illumination system battery-free?

The main ACOG reticle uses a combination of fiber optics (which gather ambient light) and tritium (a self-luminous radioactive isotope with a lifespan of about 12 years). In daylight, the fiber-optic filament is bright; in darkness, the tritium glows for low-light aiming. No battery means no dead batteries in the field, though the RMR red dot on top does require a battery for operation.

Is the RMR red dot included, or do I need to buy it separately?

The Trijicon RMR Type 2 (3.25 MOA) is included with this package, already mounted and ready. You also get the TA51 mount, lens pen, adjustment cap lanyard, manual, and warranty card.

Can I use this scope on a 5.56 NATO rifle, or is it only for .223?

The scope is calibrated for .223. While .223 Remington and 5.56 NATO fire the same-diameter bullet and are often similar in ballistics, they are not identical cartridges. The reticle's bullet drop compensation is specifically zeroed for .223. Consult your rifle's documentation and ballistics data if you plan to use it with 5.56.
