Trijicon ACOG BDC: Precision Rifle Scope for 5.56mm Defense Use

The modern patrol rifle demands optics that balance ruggedness, fast target acquisition, and ballistic intelligence. For operators running 5.56 platforms who need a proven, no-nonsense sighting solution, there are few optics that match the pedigree and field-proven design of the ACOG series.

TRIJICON ACOG TA31H (.223/5.56 BDC) is built around a single-piece aluminum housing delivering industry-leading toughness and a wide field of view paired with crystal clear glass. The TA31H features 4×32 magnification with a self-illuminated reticle that uses fiber optic and tritium inserts—no batteries required—which gives you a visible red horseshoe and dot reticle for quick centering on target in varied light conditions.

Key features that matter

Durability: The single-piece aluminum construction stands up to recoil, harsh handling, and environmental stress. The all-black finish resists glare and wear.

Optics and reticle: The 4×32 optic gives a practical balance between magnification and field of view. The H-model’s red horseshoe and dot reticle provides fast acquisition for close-to-medium engagements while the ranging marks are calibrated specifically for 5.56x45mm NATO out to 800 meters—valuable for shooters who trust the ballistic profile of .223/5.56 ammunition.

Mounting and ergonomics

Mounting is quick and repeatable using the included TA51 series Picatinny mount. After hand-tightening the mount, a quarter-turn adjustment secures the sight to a standard Picatinny rail, enabling rapid installation or removal in the field without tools. That rapid mounting characteristic is a practical advantage for multi-role rifles and kit swaps. View product details and pricing

Operational assessment

For operators and enthusiasts running 5.56 platforms, the TA31H’s calibrated ranging reticle, fiber optic/tritium illumination and rugged one-piece housing deliver a combination of ballistic usefulness and battlefield durability. At a price of $1,229.99, this optic is positioned as a premium choice for those prioritizing proven performance and minimal maintenance.
