Trijicon ACOG 4×32 BAC ECOS Riflescope 5.56 BDC Green Crosshair Reticle
Features
- Dual‑Illuminated, Battery‑Free ACOG: Fiber optics automatically regulate reticle brightness in daylight; tritium lamp provides a glow in low/no light—no batteries required in the ACOG body.
- ECOS Dual‑Sighting System: Factory‑mated Trijicon RMR® Type 2 LED Red Dot (3.25 MOA) mounted atop the ACOG for instant, heads‑up CQB transitions without changing cheek weld.
- 5.56 BDC Green Crosshair Reticle: Highly visible green crosshair with ballistic drop stadia scaled for 5.56 NATO / .223 trajectories (100 m zero) for rapid holds to extended distance.
- Backup Iron Sights & Quick‑Release Mount: Integrated mini iron sights on the included Trijicon QD Picatinny mount provide a tertiary aiming option; fast on/off with repeatable zero.
- Bindon Aiming Concept™ Speed: True both‑eyes‑open shooting at 4× magnification—maintain situational awareness while driving the crosshair on target.
- Battle‑Proven Durability: Forged aluminum housing, Cerakote® Flat Dark Earth finish, shock‑resistant, waterproof, fog‑proof—built for combat environments.
- External Tool‑Less Adjusters: 1/2 MOA windage & elevation clicks; no turret caps needed.
- Compact, Lightweight Deployment Kit: Designed for carbines where height, balance, and weight matter.
- Made in USA & Backed by Trijicon Warranty.
