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

Features

  • Dual‑Illuminated, Battery‑Free: Fiber optics provide bright daytime illumination; tritium lamp glows in low/no light—no batteries or switches to manage.
  • 4× Fixed BAC Combat Optic: Bindon Aiming Concept™ supports both‑eyes‑open speed for close engagements while delivering precise 4× magnification for intermediate/long 5.56 shots.
  • .223/5.56 BDC Red Horseshoe/Dot Reticle: Highly visible red illuminated horseshoe encircling a fine central dot; descending ballistic stadia calibrated for common 5.56 NATO loads (100 m zero). Horseshoe speeds CQB snap; dot + BDC lines add precision at distance.
  • Rugged Forged 7075‑T6 Aluminum Housing: Combat‑proven ACOG chassis—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: Positive 2 clicks/inch @100 yd for fast, repeatable zeroing.
  • Waterproof to 100 m; Nitrogen‑Purged: Built to exceed tough duty requirements.
  • Compact & Lightweight: Short 5.8″ body keeps carbines lively; ships ready for flattop install.
  • Made in USA & Backed by Trijicon Warranty.
