Features

  • Dual‑Illuminated, Battery‑Free ACOG: Fiber optics (auto day brightness) + tritium lamp (low/no light) — always on; no batteries in the ACOG body.
  • 4× Fixed BAC Combat Optic: Bindon Aiming Concept™ supports both‑eyes‑open speed at CQB distances while preserving precise 4× aiming for mid‑range 5.56 work.

  • Factory‑Mounted Trijicon RMR® Type 2 (3.25 MOA Red Dot): Instant 1× heads‑up sighting for close targets without breaking cheek weld; ruggedized electronics.
  • Rugged Forged 7075‑T6 Aluminum Housing: Combat‑proven ACOG chassis; shock, recoil, and environmental abuse resistant; sealed and fog‑proof.
  • External Tool‑Less Adjusters: Positive ½ MOA windage & elevation clicks; quick zero corrections in the field.
  • Wide Situational Field of View: 7° / 36.8 ft @ 100 yd helps track movers and maintain awareness.
  • Mission‑Ready Mounting: Ships with TA51 flattop Picatinny thumbscrew adapter; RMR pre‑aligned on top.
