Trijicon ACOG 3.5×35 | Green Horseshoe .223 BDC | 100156

The Trijicon ACOG 3.5×35 is a fixed-power riflescope engineered for fast target acquisition and consistent ballistic compensation for .223/5.56-caliber platforms. It features a dual-illuminated Green Horseshoe ballistic reticle with fiber optics for daytime illumination and tritium for low-light conditions. The optic is built on a forged-aluminum housing and includes a TA51 flattop mount adapter for use on MIL-STD style rails. The reticle’s Target Reference System is calibrated for 5.56/.223 to provide rapid, repeatable holdovers.

Applications: Precision target shooting at intermediate ranges, and varmint or medium-game field use where a compact BDC optic is preferred.

Compact, rugged, and purpose-built, this ACOG variant puts calibrated holdovers and illuminated aiming points into a small, reliable package. The fixed 3.5x magnification is balanced for rapid engagements while retaining useful detail at intermediate ranges, and the fiber optic/tritium illumination system keeps the reticle usable in varied lighting without batteries. The included TA51 adapter simplifies mounting to flat-top receivers and maintains a low, repeatable cheekweld for consistent shooting ergonomics.

Users commonly praise the ACOG for its durability and its fast target acquisition; many also note excellent optical clarity for its size and magnification.
