Trijicon ACOG 4×32 BAC Riflescope .223/5.56 BDC Green Crosshair Reticle

Features

  • Dual‑Illuminated, Battery‑Free ACOG: Fiber optics automatically regulate reticle brightness in daylight; tritium provides a continuous glow in low/no light—no batteries required.
  • 4× Fixed BAC Combat Optic: Bindon Aiming Concept™ supports both‑eyes‑open speed for close work while preserving precise 4× aiming at distance on 5.56/.223 carbines.
  • .223/5.56 BDC Green Crosshair Reticle: Fine illuminated crosshair with ballistic stadia scaled for common 5.56 loads when zeroed at 100 m; green illumination is highly visible in bright, high‑contrast field conditions.
  • Rugged Forged 7075‑T6 Aluminum Housing: Combat‑proven durability—shock, recoil, and hard‑use environmental resistance; fully sealed and fog‑proof.
  • Waterproof to 100 m (factory rated): Exceeds typical duty requirements; nitrogen‑purged to prevent internal fogging.
  • External Tool‑Less Adjusters: Positive ½ MOA windage & elevation clicks (2 clicks/inch @ 100 yd) for fast zeroing without loose turret caps.
  • Wide Situational FOV: 7° / 36.8 ft @ 100 yd helps track movers and maintain awareness.
  • Compact & Lightweight: Short 5.8″ body keeps weight forward‑neutral on AR‑pattern rifles; ships with TA51 flattop Picatinny mount.
  • Made in USA & Backed by Trijicon Warranty.
