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

Features

  • Dual‑Illuminated, Battery‑Free: Fiber optics auto‑adjust 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× magnification for mid‑range 5.56 engagements.
  • .223/5.56 BDC Red Crosshair Reticle: Fine illuminated crosshair with descending ballistic stadia scaled for common 5.56 NATO loads when zeroed at 100 m; simple, uncluttered holds to distance.
  • Rugged Forged 7075‑T6 Aluminum Housing: Combat‑proven durability—shock, recoil, and harsh‑environment resistant; fully sealed and fog‑proof.
  • Wide Situational FOV: 7° (36.8 ft @ 100 yd) helps track movers and maintain awareness.
  • ½ MOA External Adjusters: 2 clicks/inch @100 yd for quick zeroing without removing turret caps.
  • Waterproof & Nitrogen‑Purged: Built for field extremes.
  • Compact & Lightweight: Short 5.8″ body keeps carbines lively; ships ready for flattop install.
  • Made in USA & Backed by Trijicon Warranty.
