Trijicon 100813 ACOG 4X32 3.25 MOA RED DOT

The Trijicon ACOG 4x32 with 3.25 MOA red dot reticle is a battle-proven magnified sight built for shooters who need both close-range speed and medium-distance precision. This is a fixed 4-power scope engineered around the .223/5.56 platform, pairing a robust 32mm objective with a chevron-style aiming point that lets you drive fast shots when targets are close or dial in more deliberately when distance matters. Whether you're running a patrol rifle, a designated marksman setup, or a competition gun that demands versatility, the ACOG's forged aluminum construction and matte black finish stand up to hard use without flinching.

What sets this optic apart is its dual-power philosophy: fiber optics and tritium combine to keep the reticle visible in daylight and low light without batteries. The 3.25 MOA dot splits the difference between a precision point and a faster sight picture, and the built-in bullet drop compensator for .223/5.56 means you're not managing holdover in the field. At 1.5 inches of eye relief, it's comfortable behind most stocks, and the flattop TA51 thumbscrew mount indexes quickly and repeats zero reliably.

This combo includes the RCR closed-emitter red dot sight, giving you true dual-aiming capability—stick with the 4x ACOG for precision work, or mount the RCR for lightning-fast target acquisition in confined spaces. The bundled accessories—lens pen, lanyard assembly for adjuster caps, and detailed manual—mean you're ready to mount and shoot. Submersion-rated to 66 feet, it'll handle field conditions you hope you never see.

Frequently Asked Questions

What rifle platforms is the ACOG 4x32 built for?

This scope is calibrated for .223/5.56 rifles and includes a flattop TA51 mount designed for Picatinny rails on AR-15s and other modern sporting rifles with flat-top receivers.

Do I need batteries for the red dot reticle?

No. The reticle is illuminated by fiber optics during daylight and tritium LED in low light, so there are no batteries to replace or run dead.

Can I use both the ACOG and the RCR red dot at the same time?

The RCR is included as a standalone sight for close-quarters use. You'd choose one aiming solution based on your situation—the magnified ACOG for precision and distance, or the RCR for speed and close range—rather than running both simultaneously.

What does the 3.25 MOA reticle mean?

The chevron dot is 3.25 minutes of angle wide. At 100 yards, that's roughly 3.5 inches. It's large enough to acquire quickly but precise enough to make accurate shots at practical hunting and combat distances.
