Trijicon ACOG 5.5×50 BAC Riflescope .223/5.56 BDC Red Chevron Reticle
Features
- Big‑Objective, Long‑Range ACOG: 5.5× fixed magnification paired with a large 50 mm objective delivers excellent light transmission and target definition at extended distances.
- Dual‑Illuminated, Battery‑Free: Fiber optics automatically adjust reticle brightness in daylight; tritium lamp glows in low/no light—always on, no batteries to manage.
- Red Chevron .223/5.56 BDC Reticle: Zero the chevron tip at 100 m; descending stadia give holds for typical 5.56 NATO trajectories. Chevron base subtension (~5.5 MOA ≈ 19" @300 m) aids rapid range estimation on silhouette targets.
- Bindon Aiming Concept™ Capable: Bright, illuminated reticle supports both‑eyes‑open speed for closer shots while retaining 5.5× precision at distance.
- Forged 7075‑T6 Aluminum Housing: Monolithic, combat‑proven ACOG chassis built to survive heavy recoil, impact, and harsh environments.
- Fine External Adjusters: Approx. 0.2 MOA per click (~5 clicks/inch @100 yd) for more precise zeroing than standard 4× models.
- Deep‑Water Sealed & Nitrogen‑Purged: Waterproof well beyond typical field exposure; resistant to internal fogging.
- TA51 Flattop Picatinny Mount Included: Ready for AR‑pattern / MIL‑STD‑1913 upper receivers out of the box.
- Made in USA & Backed by Trijicon Warranty.
