Trijicon ACOG 3.5x35 Rifle Scope - .308 Amber Crosshair, Matte Finish with Picatinny Adapter
Trijicon
The Trijicon ACOG 3.5x35 rifle scope is a battle-proven combat optic designed for shooters who need fast target acquisition and reliable performance in any light. Built around the Bindon Aiming Concept, this fixed-magnification scope excels in close-to-intermediate range engagements while maintaining a wide field of view that rewards both eyes-open shooting and situational awareness. The .308 red crosshair reticle is specifically calibrated for 7.62mm (.308 Winchester) rifles on flat-top receivers, with ranging marks precise to 1200 meters—making this scope equally at home on a carbine, patrol rifle, or precision .308 platform.
What sets the ACOG apart is its hybrid illumination system. Fiber optics gather ambient light during the day to keep the reticle center glowing bright red without battery drain, while tritium takes over automatically at night or in dark conditions. You'll never hunt or shoot in a situation where your reticle isn't visible. The forged aluminum housing and matte finish are built to take abuse; the compact 8-inch length and 14-ounce weight keep your rifle balanced and fast. The included TA51 Picatinny adapter lets you mount it on any flat-top rail, and Trijicon includes a protective scopecoat, cleaning pen, lanyard cap assembly, and manual to get you running immediately.
This is a optic for serious shooters—military and law enforcement have trusted the ACOG platform for decades. If you're running a .308 rifle for hunting, sport shooting, or tactical use and want a scope that operates without batteries, survives hard use, and delivers fast, reliable aiming, the ACOG 3.5x35 is worth the investment.

The ACOG is 3.5x magnification with a 5.5-degree field of view. That wide field of view with fixed 3.5x power makes it excellent for hunting and shooting at close-to-intermediate ranges, where the design really shines. The Bindon Aiming Concept keeps both eyes open for better awareness and faster target acquisition than traditional magnified scopes.
