Trijicon ACOG 3.5x35 Rifle Scope - Matte Finish, .223 Red Horseshoe Reticle, Includes Picatinny Adapter

The Trijicon ACOG 3.5x35 rifle scope is a battle-proven magnified optic built for shooters who demand reliability in the field. With its compact 3.5x magnification and 35mm objective, this scope delivers a bright sight picture suitable for mid-range work on 5.56/.223 rifles. The red horseshoe reticle with Target Reference System (Bindon Aiming Concept) is calibrated for 5.56 ammunition out to 1000 meters, giving you holdover marks that correspond to real-world bullet drop so you can adjust your aim without dialing corrections on the fly.

Durability is the ACOG's calling card. The forged aluminum housing is built to handle the recoil and abuse of serious shooting, while dual illumination—fiber optics for daylight brightness and tritium for low-light and night use—means your reticle stays visible whether you're shooting mid-morning or after dark. You don't need batteries; the scope is always ready. The 2.4 inches of eye relief gives you a comfortable cheek weld on most platforms, and the 10mm exit pupil keeps your eye box forgiving in tactical situations.

This package includes Trijicon's flat-top Picatinny adapter (TA51) for mounting on standard AR-pattern receivers, plus a protective scopecoat, LENSPEN for lens care, lanyard for adjuster caps, and the full manual. At just 14 ounces and 8 inches long, it won't bloat your rifle's profile or weight budget, making it a smart choice for hunters, carbine shooters, and 3-gun competitors alike.

Frequently Asked Questions

Is this ACOG 3.5x35 compatible with my AR-15?

Yes. This scope comes with a flat-top Picatinny adapter (TA51) designed for standard AR-pattern carry-handle receivers and picatinny rails. It will mount directly to any flat-top AR-15 or similar rifle platform with a 1913 Picatinny rail.

What ammunition is the reticle calibrated for?

The red horseshoe reticle and Target Reference System are calibrated for 5.56/.223 ammunition, with holdover marks good out to 1000 meters. If you're shooting 5.56 in a 5.56 rifle, the holdover marks will align with your bullet drop.

Does this scope require batteries or external power?

No. The ACOG uses two independent illumination sources—fiber optics gather ambient light during the day to brighten the reticle, and tritium provides self-illumination at night or in darkness. There are no batteries to install or replace, so the scope is always ready to go.

What's included in this package?

You get the scope itself, a flat-top Picatinny adapter, a protective scopecoat, a LENSPEN for cleaning the optics, a lanyard assembly for the adjuster caps, the ACOG user manual, and a warranty card.
