Trijicon ACOG 4x32 BAC .300 BLK BDC

• Dual-illuminated BAC reticle: The fiber-optic and tritium illumination system keeps the aiming point visible across changing light conditions without relying on a battery, while the Bindon Aiming Concept supports fast, both-eyes-open shooting.
• .300 BLK merged BDC reticle: The reticle is designed to work with both supersonic and subsonic .300 Blackout loads, letting the shooter switch ammunition types without re-zeroing and still keep practical hold points.
• Fixed 4x prism design: A compact fixed-power layout reduces moving parts and keeps the optic short, strong, and easy to mount on carbines that need dependable magnification for medium-distance work.
• Wide field of view: With 12.27 m/100m of field of view, the scope gives more surrounding visual information, which helps track movement and maintain awareness in dynamic shooting situations.
• Forged aluminum housing: The robust body, combined with waterproof, fogproof, and shockproof construction, supports reliable use in hard field conditions and across a broad temperature range.

About the Trijicon ACOG Series

Trijicon ACOG is a long-established family of compact fixed-power prism riflescopes built for medium-distance engagements. The series began in 1987 with the original 4x32 TA01 and has since grown into one of Trijicon’s best-known lines for military, law-enforcement, and civilian shooting applications. ACOG models are defined by their fixed-magnification design, which keeps the optical system compact and mechanically simple while providing a bright, clear image and dependable point of aim.

A key characteristic of the series is the Bindon Aiming Concept, which supports rapid target acquisition with both eyes open. Many ACOG models also use tritium and fiber optics to illuminate the reticle without batteries, while selected versions use LED illumination instead. Across the range, Trijicon offers different magnifications, reticle patterns, and caliber-specific bullet-drop compensating layouts, including variants developed around service-rifle use. The result is a riflescope family that emphasizes fast sight pictures, compact dimensions, and practical holdover references for shooters who want more precision than a non-magnified sight but less bulk than a traditional variable optic.

About the Trijicon ACOG 4x32 BAC .300 BLK BDC

The Trijicon ACOG 4x32 BAC .300 BLK BDC is a fixed-power tactical riflescope built around the needs of the .300 Blackout cartridge. Its defining feature is the red crosshair reticle with a merged bullet-drop layout that allows practical use with both supersonic and subsonic ammunition. That matters on a .300 BLK carbine because the shooter can move between common load types without re-zeroing the optic, while still retaining useful aiming references for real field distances.

The 4x magnification gives enough image scale for more deliberate shot placement than a red dot, yet the optic remains quick to use thanks to the Bindon Aiming Concept. With both eyes open, the shooter can maintain awareness at closer distances while still benefiting from magnification when the shot stretches out. The 32 mm objective lens, multi-coated optics, and 8.13 mm exit pupil help deliver a bright, easy-to-acquire sight picture, while the 12.27 m/100m field of view supports target transitions and observation.

This model also keeps the classic ACOG emphasis on durability. The forged aluminum housing and compact 151.89 mm overall length make it well suited to hard-use carbines where space, balance, and resilience matter. Waterproof, fogproof, and shockproof construction further support use in demanding weather and rough handling. Supplied with the TA51 thumbscrew mount, it is configured for straightforward installation on a flattop rifle platform.

About Trijicon

Trijicon was founded in 1981 by Glyn Bindon and is based in Wixom, Michigan, United States. The company develops aiming systems for military, law-enforcement, hunting, and shooting use, with product lines that include riflescopes, red dot sights, electro-optics, and iron sights. In 1985, the company adopted the name Trijicon, combining “tritium” and “icon,” reflecting the illumination technology that became central to its identity.

Within the shooting optics market, Trijicon is particularly known for its work with tritium, fiber-optic, and LED illumination systems. The company introduced the ACOG in 1987, and that optic went on to become one of its most recognized products. Trijicon’s reputation in combat-oriented optics is reinforced by the use of ACOG and VCOG models in U.S. military service, while its broader catalog also serves civilian shooters who want durable, application-focused sighting systems.
