Trijicon ACOG TA33 3x30mm Compact Rifle Scope with Dual-Illuminated Horseshoe/Dot Ballistic Reticle & RMR Type 2 Red Dot Sight, Q-LOC Mount - Matte Finish

The Trijicon ACOG TA33 3x30mm compact rifle scope is a combat-proven dual-sighting platform that combines fixed 3x magnification with an integrated RMR Type 2 red dot, giving you both close-quarters speed and mid-range precision in a single mounted system. Built for shooters who need to transition between CQB engagements and shots requiring magnified aiming, this combo eliminates the choice between optics—you get both, matched and zeroed together from the factory.

The TA33 features a horseshoe/dot ballistic reticle with dual illumination (fiber optics and tritium), so it stays visible in bright sunlight, dim interiors, and total darkness without batteries. The reticle is calibrated for 5.56x45mm 62-grain ammunition and incorporates the Bindon Aiming Concept (BAC), which uses the sight's wide field of view to let both eyes stay open for better situational awareness—a genuine tactical advantage in dynamic shooting. Adjustments are 0.25 MOA per click, giving you precise zero adjustments and hold-over correction when you need it.

The Trijicon Q-LOC mount is a compact, lightweight platform forged from 6061-T6 aluminum and finished in matte black anodize. Its spring-loaded design maintains zero even before you fully tighten the knobs, and the one-handed, tool-free mounting system lets you get the optic on and off your rail quickly. The mount fits any Mil-Spec or NATO Picatinny rail and is rated for Mil-Spec drop tests. Made in the USA, this is the kind of gear that works when it matters.

At 1.9 inches of eye relief and a compact footprint, the ACOG TA33 works on modern carbines, patrol rifles, and short-barreled platforms where real estate is tight. If you're outfitting a rifle for versatility—whether for duty, defensive work, or serious sport shooting—this combo does the job without forcing compromises.

Frequently Asked Questions

Will the ACOG TA33 with RMR combo fit my AR-15 or M4?

Yes. The Q-LOC mount is compatible with any Mil-Spec or NATO Picatinny rail. The compact dimensions and low-profile design make it well-suited to modern carbines and short-barreled rifles where space is limited.

Do I have to use both the ACOG and the RMR, or can I use just one?

The ACOG TA33 comes with the RMR Type 2 already mounted and integrated into the system. Both sights are zeroed and ready to use together. The dual-sight setup gives you the flexibility to employ the RMR for close-range targets and the magnified ACOG for distance, or to transition between them depending on your tactical situation.

What's the reticle calibrated for, and will it work with other ammunition?

The ballistic reticle is calibrated for 5.56x45mm NATO rounds loaded with 62-grain projectiles. Point of impact will shift with significantly different ammunition (different cartridges or bullet weights), so if you use other loads regularly, you may need to adjust your zero or plan your holds accordingly.

How does the illumination work? Do I need batteries?

The reticle is illuminated by fiber optics (which collect ambient light) and tritium (radioactive self-illumination). This dual-source design means the reticle stays visible in daylight, low light, and darkness without requiring any batteries. The fiber-optic element enhances brightness in bright conditions, while the tritium provides a dim glow at night or in total darkness.

Is the Q-LOC mount tool-free to attach?

Yes. The Q-LOC mount features a one-handed, tool-free mounting system with a spring-loaded design that maintains zero retention even before the knobs are fully tightened. It's rated for Mil-Spec drop tests and offers superior return-to-zero performance.
