Trijicon ACOG 3.5x35 Rifle Scope - .308 Red Chevron Reticle, Matte Finish, Includes Picatinny Adapter

The Trijicon ACOG 3.5x35 rifle scope is a combat-proven optic built for shooters who need a dependable, fast-acquiring sight on .308 rifles. Built around the Bindon Aiming Concept—a method that lets you engage targets with both eyes open—this fixed-power scope combines a fiber-optic and tritium illumination system so your reticle stays visible from bright daylight to total darkness without batteries. The red chevron reticle is purpose-designed for distance estimation and zeroing: the tip centers at 100 meters, and the chevron's base width (5.53 MOA) enables holdover calculations out to 800 meters on a 7.62 NATO platform.

At 3.5x magnification with a 35mm objective, the ACOG delivers a wide, intuitive sight picture—perfect for close-quarters work or mid-range precision. The forged aluminum housing is tough enough for professional use and suppressor-ready. Matte finish resists glint, and the scope comes mounted on a Picatinny-compatible TA51 adapter, so installation on a flat-top AR or other platform is straightforward. Weight is just 14 ounces without the mount, keeping your rifle balanced and handy.

Trijicon includes a complete accessory package: scopecoat lens cover, LensPen, lanyard assembly for the adjuster caps, manual, and warranty card. This is a scope that works the first day you mount it and keeps working, whether you're training at the range or in the field where reliability isn't optional.

Frequently Asked Questions

What .308 rifles is the ACOG 3.5x35 compatible with?

This scope is designed for 7.62 NATO/.308 caliber flat-top rifles. The reticle and ballistic compensator are specifically calibrated for that cartridge. The included TA51 adapter fits any Picatinny rail on an AR-10, modern M4/AR-15 upper, or other flat-top rifle platform.

Does it come with a mount, and is installation easy?

Yes—the TA51 Picatinny adapter is included. You simply slide it onto your rifle's Picatinny rail and secure it with the thumbscrew. No gunsmithing required.

How does the illumination system work?

The reticle combines fiber optics and tritium. During the day, fiber gathers ambient light to brighten the red chevron. At night or in low light, tritium self-illumination takes over. No battery is needed, so the reticle is always ready.

What's the difference between the chevron reticle and other ACOG patterns?

The red chevron is a ranging reticle designed for distance estimation and holdover calculations. The width of the chevron's base is 5.53 MOA—at 300 meters, that measures 19 inches on a human silhouette target, giving you quick, intuitive range confirmation. The tip is your primary aiming point at 100 meters.
