Trijicon 4x32 ACOG Rifle Scope Matte .223 Red Horseshoe/Dot with Picatinny Adapter

The Trijicon 4x32 ACOG rifle scope is a battle-proven combat optic that pairs legendary durability with intuitive aiming for mid-range engagements on .223/5.56 platforms. Built on the Bindon Aiming Concept, this scope delivers fast target acquisition and accurate fire from 0 to 800 meters without batteries—relying on fiber-optic daylight collection and tritium self-illumination for the horseshoe reticle. Whether you're training at the range, hunting medium game, or setting up a home defense rifle, the ACOG's fixed 4x magnification and 32mm objective offer the balance of brightness, field of view, and durability that professionals and serious shooters have relied on for decades.

This model comes mounted on Trijicon's Picatinny-compatible TA51 flattop adapter, so installation is straightforward on any AR platform with a flat-top receiver. The matte finish resists glint, the forged-aluminum housing is built to absorb recoil, and the 8mm exit pupil means you'll get a consistent sight picture even when you're not perfectly centered behind the scope. At 9.9 ounces (without mount), it's compact and light enough that it won't burden your rifle's handling or balance.

Trijicon includes the scope, flattop mount, protective scopecoat, cleaning pen, lanyard assembly for the adjustment caps, and documentation—everything you need to mount and maintain the optic. The red horseshoe reticle is calibrated specifically for .223 and offers precise aiming marks for rapid target engagement. If you're building a reliable, no-nonsense .223 rifle and want an optic that works in bright sun and low light without electronics, the ACOG 4x32 is the industry standard.
