Trijicon ACOG 4x32 LED .300 BLK BDC

• LED illumination with six brightness settings: user-selectable reticle brightness helps the optic stay visible in bright daylight, shaded cover, and transitional light, while the off position between settings makes it quick to return to a preferred level.
• .300 BLK BDC crosshair reticle: the reticle is tuned for .300 Blackout use and combines hold points for supersonic and subsonic loads, reducing the need to re-zero when switching ammunition types.
• Fixed 4x prism design: a compact fixed-power layout keeps the optic short, robust, and fast to use, while still giving enough magnification for confident target identification and holdovers at medium distance.
• AA-powered long runtime: a common AA battery keeps the optic running for extended use, which is practical for duty rifles, training carbines, and hunting setups that need simple battery logistics.
• Forged aluminum housing: the rugged body, nitrogen filling, and waterproof, fogproof, shockproof construction support reliable use on hard-recoiling rifles and in wet or rapidly changing weather.

About the Trijicon ACOG Series

Trijicon ACOG is a long-established family of fixed-power prism riflescopes built for medium-distance engagements. Introduced with the first 4x32 TA01 in 1987, the series became known for combining a compact footprint with a durable prism-based design that suits service rifles, defensive carbines, and practical field use. Across the range, Trijicon offers different magnifications, reticle patterns, and illumination systems, including both traditional tritium and fiber-optic models and selected LED-illuminated versions.

A defining characteristic of the ACOG line is its emphasis on speed and simplicity. The fixed-power layout minimizes moving parts, helping the optic remain compact and mechanically robust, while the Bindon Aiming Concept supports rapid, both-eyes-open shooting at closer distances. Many ACOG models also use bullet-drop compensating reticles with ranging references, giving shooters practical hold points instead of relying on dial-up adjustments. Within Trijicon’s lineup, the ACOG series sits as a proven prism-scope platform for users who want a rugged magnified optic with fast target acquisition, clear glass, and a reticle designed to work directly with real-world rifle and ammunition combinations.

About the Trijicon ACOG 4x32 LED .300 BLK BDC

The Trijicon ACOG 4x32 LED .300 BLK BDC is a fixed-power prism riflescope built around the needs of the .300 Blackout shooter who wants one optic for fast carbine handling and confident medium-range holds. Its 4x magnification gives more target detail than a non-magnified sight without making the optic bulky, and the 32 mm objective helps maintain a bright, usable image in mixed light. With a wide field of view and the ACOG’s both-eyes-open shooting concept, it remains practical on rifles used for defensive roles, range training, and hunting at realistic carbine distances.

This version stands out for its LED-illuminated FFP crosshair reticle and caliber-specific BDC. The reticle is designed so the shooter can move between supersonic and subsonic .300 BLK loads without re-zeroing, using merged aiming points that simplify holdovers in the field. That makes it especially useful for rifles that may be used with different ammunition types for different tasks. The LED system offers six brightness settings with an off position between each level, so the reticle can be tuned for bright sun, indoor use, or transitional light rather than relying on a fixed illumination response.

Mechanically, the optic follows the ACOG formula of compact strength. The forged aluminum housing, nitrogen-filled construction, and waterproof, fogproof, shockproof build support hard use, while the AA power source keeps battery replacement simple and widely manageable. The included Picatinny-compatible thumbscrew mount format also suits straightforward installation on modern flat-top rifles.

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, it adopted the name Trijicon, combining the words tritium and icon, reflecting the illumination technology that helped define the brand.

In the riflescope and sighting market, Trijicon is particularly known for the ACOG, introduced in 1987, and for its broader work with tritium, fiber-optic, and LED illumination systems. The company’s optics have seen extensive professional use, including ACOG models used by the U.S. Marine Corps as the Official Rifle Combat Optic. That background gives Trijicon a strong reputation for compact, duty-oriented optics that prioritize durability, practical reticle design, and dependable illumination.
