Trijicon ACOG 5.5×50 BAC Riflescope .308/7.62 BDC Red Chevron Reticle

Features

  • 5.5× / 50 mm Long‑Range ACOG: Larger objective delivers excellent low‑light brightness and target resolution at distance.
  • Dual‑Illuminated, Battery‑Free: Fiber optics auto‑adjust in daylight; tritium lamp glows in low/no light—always on, no batteries to manage.
  • Red Chevron .308/7.62 BDC Reticle: Zero tip at 100 m; descending stadia give holds for common 7.62×51/.308 trajectories. Chevron base (~5.53 MOA ≈ 19" @300 m) doubles as a quick range estimator on silhouettes.
  • Bindon Aiming Concept™ Capable: Bright reticle supports both‑eyes‑open speed up close while retaining 5.5× precision for longer shots.
  • Forged 7075‑T6 Aluminum Housing: Combat‑proven durability—shock, recoil, and harsh‑weather resistant; matte black hard anodize.
  • Fine External Adjusters: 5 clicks/inch @100 yd (~0.2 MOA) lets you refine zero more precisely than standard 4× ACOGs.
  • Deep‑Water Sealed & Nitrogen‑Purged: Waterproof far beyond typical field exposure; fog‑resistant.
  • TA51 Flattop Picatinny Mount Included: Ready for AR‑10 / SR‑25 / M1A‑rail builds out of the box.
  • Made in USA & Backed by Trijicon Warranty.
