Trijicon 4x32 ACOG Rifle Scope - Matte Finish, Red Chevron Reticle, Includes Adapter

The Trijicon 4x32 ACOG rifle scope is a battle-proven magnified optic built for shooters who need reliable aiming solutions in any light condition. Originally designed to the specifications of the United States Marine Corps for the M4 platform, this scope combines fiber optic and tritium illumination to keep your reticle visible from bright daylight through total darkness—without batteries. The red chevron reticle is engineered for rapid target acquisition at close quarters while offering extended range capability out to 800 meters with the integrated bullet drop compensator. Whether you're running a dedicated rifle for hunting, competition, or serious marksmanship, the ACOG delivers the kind of dependable performance that's earned its reputation across decades of field use.

What sets this scope apart is its hybrid illumination system: the fiber optic element automatically adjusts reticle brightness in daylight, self-regulating as ambient light changes, while tritium takes over to glow reliably in darkness. You get both eyes-open shooting for maximum situational awareness and a reticle that's always ready. The external windage and elevation adjusters require no tools and maintain the scope's waterproof integrity up to 11 meters. At just over 16 ounces and 7.3 inches long, it balances optical power with the handling characteristics serious shooters expect from a combat-grade optic.

Included in the package is the Picatinny rail thumbscrew mount (TA51), a killFLASH anti-reflection device to eliminate lens glare, an objective lens flip cap, a lanyard for the adjuster caps, and a LENSPEN cleaning tool—everything you need to get the scope mounted and ready for the field. The forged aluminum housing is finished in matte to reduce reflection and withstand hard use. This is a complete, no-compromise optic package that doesn't require hunting down accessories separately.

Frequently Asked Questions

What's included with this ACOG scope?

The scope comes with a Picatinny rail thumbscrew mount (TA51) ready for AR platforms, a killFLASH anti-reflection device to eliminate lens glint, an objective flip cap for lens protection, a lanyard assembly for the adjuster caps, and a LENSPEN cleaning tool. You're getting a complete package without the need to source accessories separately.

Will this scope work on rifles other than the M4?

This scope is calibrated for the 5.56 NATO (.223) cartridge from a 14.5-inch barrel and is designed around the M4 platform. While the optical quality and illumination will work on other rifles, the bullet drop compensator reticle is specifically zeroed for that ballistic profile. Check your rifle's compatibility with Picatinny rail mounting before purchase.

How does the illumination work without batteries?

The scope uses a hybrid system: a fiber optic element that gathers and auto-adjusts ambient light during the day, and self-luminous tritium that glows passively in darkness. There are no batteries to replace or charge. The tritium will glow reliably for many years without any maintenance.

Can I mount a red dot sight on this ACOG?

Yes. The scope has integrated mounting bosses at the eyepiece that allow you to add a Trijicon RMR red dot sight (sold separately), which is a common setup for shooters wanting both magnification and close-range aiming options.
