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

The Trijicon ACOG 3.5x35 rifle scope is a proven optic for shooters running intermediate cartridges on modern rifles. Built around the green chevron reticle and calibrated specifically for .223/5.56 ammunition, this compact scope delivers both daylight brightness and low-light capability without batteries. It's a workhorse for tactical shooters, hunters working closer ranges, and anyone who values reliability and speed over maximum magnification.

The green chevron reticle is zeroed at the tip for 100 meters and scales to support range estimation out to 800 meters on 5.56 platforms. At 300 meters, the chevron base spans 5.53 MOA, allowing you to read distance on silhouette targets in field conditions. The 3.5x magnification and 35mm objective give you a bright sight picture and a 5.5-degree field of view—enough to track movement and acquire targets quickly, without the tunnel vision of higher magnification.

This scope runs on fiber optics during the day and tritium at night, so you're never dependent on a battery dying at a critical moment. The matte aluminum housing is built tough; the included TA51 Picatinny adapter (flat-top mount) fits any modern rifle rail. Trijicon ships this package with lens cleaning gear, a lanyard assembly for the turret caps, a protective scope cover, and the manual—everything you need to mount and deploy.

At 14 ounces and just under 8 inches long, it won't bloat your rifle setup. Eye relief of 2.39 inches keeps you safe behind the scope on recoil, and the 10mm exit pupil means fast target acquisition across a wider range of shooting positions.

Frequently Asked Questions

What rifles does the Trijicon ACOG 3.5x35 fit?

The scope comes with a TA51 Picatinny adapter, which mounts to any modern rifle with a flat-top Picatinny rail. The reticle is specifically calibrated for .223/5.56 ammunition, so it's ideal for AR-15s and other modern sporting rifles chambered in that caliber.

Does this scope need batteries?

No. The reticle uses both fiber optics (which gather ambient light during the day) and tritium (which glows at night). You'll never need to change a battery or worry about one failing in the field.

What's included in the box?

The ACOG 3.5x35 ships with the TA51 flat-top Picatinny mount adapter, a protective scopecoat, a lens pen, a lanyard assembly for the turret caps, a logo sticker, the manual, and a warranty card.

How do I use the chevron reticle for range estimation?

The reticle is zeroed at the tip for 100 meters. At 300 meters, the width of the chevron base measures 5.53 MOA, which allows you to estimate distance to silhouette targets. The manual provides detailed instructions on how to apply this method in the field.
