Trijicon ACOG 3.5x35 Rifle Scope - Matte Finish, .223 Green Crosshair, Picatinny Adapter Included

The Trijicon ACOG 3.5x35 rifle scope is a time-tested combat and tactical optic built for shooters who need fast target acquisition and reliable performance in any light. This 3.5-power scope bridges the gap between close-quarters and intermediate-range work, making it a natural choice for AR-platform rifles, home defense setups, and training scenarios where speed matters as much as precision. The scope arrives with a Picatinny adapter (TA51) pre-fitted for direct mounting to flat-top rails, plus a full complement of accessories—lens pen, scopecoat, lanyard assembly, and documentation—so you can get behind glass immediately.

What sets the ACOG apart is its dual-illumination system. Fiber optics gather ambient light during the day to energize the green crosshair reticle, while tritium takes over as darkness falls, keeping your sight picture visible without batteries or external power. The ranging reticle is calibrated to the .223 Remington (5.56 NATO) and is designed to work effectively out to 1,000 meters, giving you a ballistic reference system rather than just a simple crosshair. The scope's compact 8-inch length and lightweight 14-ounce design (sans mount) keep your rifle balanced and handy—critical for tactical carbines and hunting rifles where every ounce counts.

The optic itself is forged aluminum with a matte finish, built to withstand hard use and field abuse. The 35mm objective gathers solid light for a bright sight picture, while the 2.4-inch eye relief and 10mm exit pupil are forgiving enough for rapid target transitions. Elevation and windage adjustments click at 3 MOA per turn at 100 yards, giving you repeatable, audible feedback when zeroing or dialing for distance.

Frequently Asked Questions

Will this ACOG work on my AR-15?

Yes. The scope comes with the TA51 flat-top Picatinny adapter, which mounts directly to any AR with a flat-top receiver rail. It's ready to install out of the box.

Does the reticle glow at night without batteries?

Correct. The tritium gas vial in the reticle self-illuminates in low light and darkness, and the fiber-optic element harnesses available daylight. No batteries, no charging—it works whether you're in the field for days or just shooting after sunset.

Is this scope calibrated for .223 or 5.56 NATO?

The scope is calibrated for the .223 Remington cartridge and works with 5.56 NATO ammunition. The .223 and 5.56 share the same external ballistics for practical purposes, so you can use both with the same point-of-aim zero.

What accessories are included?

The package includes the TA51 flat-top adapter, a scopecoat lens cover, a LENSPEN lens cleaner, a lanyard assembly for the adjuster caps, the ACOG BAC manual, and a Trijicon logo sticker.
