- Tritium/fiber optic illuminated reticle works automatically in all lighting conditions
- Bullet drop compensated (BDC) reticle calibrated specifically for .223/5.56mm cartridges
- Forged, hard-anodized aluminum housing withstands extreme field abuse and recoil
- Both-eyes-open shooting capability supports rapid target acquisition at any range

Who This Is For
The Trijicon ACOG 3.5x35 HS .223 is ideal for AR-15 and M4-platform owners — whether competitive shooters, hunters, or serious home defenders — who want a combat-grade optic that eliminates battery dependency while delivering precise ranging and shot placement from 0 to 800 meters. It is equally at home on a duty rifle or a precision-focused range build.

Frequently Asked Questions
What firearms is the Trijicon ACOG 3.5x35 TA11H compatible with?
The TA11H is designed primarily for AR-15, M4, and M16 platforms chambered in .223 Remington or 5.56mm NATO. The included TA51 flattop mount attaches directly to any MIL-STD-1913 Picatinny rail. With appropriate adapter mounts, it can also be fitted to other flat-top rifles with a standard rail — however, the BDC reticle is calibrated specifically for .223/5.56mm ballistics, so best accuracy is achieved when used with that caliber.
How does the battery-free illumination work, and will the reticle dim over time?
The ACOG TA11H uses a dual-illumination system that combines a fiber optic collector on top of the scope (which harvests ambient light in daytime conditions) with a tritium phosphor lamp that glows in low-light and no-light environments. No batteries are ever required. The tritium element does have a half-life of approximately 12 years, meaning the reticle will gradually dim after roughly a decade of use — but the scope remains fully functional as a non-illuminated optic indefinitely.
Is the HS reticle the right choice for my shooting style?
The Horseshoe Dot (HS) reticle combines a large, fast-acquisition horseshoe ring for close-quarters speed shooting with a precise center dot for accurate shots at distance. This makes it an excellent all-around choice for shooters who need both CQB responsiveness and the ability to make accurate hits at 300–600 meters using the BDC stadia lines calibrated for .223 loads. If your shooting is predominantly long-range precision, a crosshair-style reticle may suit you better — but for versatile field or defensive use, the HS is hard to beat.
