Trijicon ACOG 4×32 USMC RCO Riflescope .223/5.56 BDC Red Chevron Reticle
Features
- USMC Rifle Combat Optic (RCO) Configuration: Calibrated for the M16A4 20" barrel 5.56 NATO trajectory; issued‑pattern optic with government‑spec kit components.
- Dual‑Illuminated, Battery‑Free Reticle: Fiber optics power the aiming point in daylight; tritium provides a self‑luminous glow in low/no light—always on, no batteries.
- Red Chevron .223/5.56 BDC Reticle: Chevron tip is your 100 m zero; descending stadia provide holds for extended range with M16A4 velocity curves. Chevron width may be used for coarse range estimation on silhouette targets.
- Rugged Forged 7075‑T6 Aluminum Housing: Combat‑proven ACOG durability—shock, recoil, and harsh‑environment resistant; hard‑anodized matte black finish.
- Wide Situational Field of View: 7° (36.8 ft @ 100 yd) aids scanning and mover tracking while shooting both eyes open (BAC concept).
- ½ MOA External Adjusters: 2 clicks/inch @100 yd windage & elevation; no tools required for gross correction (caps protect the adjusters).
- Waterproof / Fog‑Proof: Deep‑water sealed construction; nitrogen‑purged for internal fog resistance.
- USMC Kit Accessories: Typically ships with KillFlash® ARD, flip caps, TA51 flattop mount, and cleaning/maintenance items (see Included Accessories).
- Made in USA & Backed by Trijicon Warranty.
