Trijicon ACOG 4×32 LED Riflescope .223/5.56 BDC Green Chevron Reticle
Features
-
User‑Selectable LED Illumination (Battery Powered): Six brightness levels with an “off” detent between each setting let you dial exactly the reticle intensity you want for any light condition; powered by a single AA (alkaline or lithium) battery.
-
Extended Battery Life: Runs 12,000+ continuous hours on setting #4 at ~21 °C (70 °F); choose lithium cells for maximum runtime range performance.
-
NVD‑Friendly Low Settings: Lower brightness levels are compatible with image‑intensified night‑vision devices without excessive bloom.
-
4× Fixed ACOG Optical System: Proven prism design delivers fast target acquisition and rugged, repeatable 4× magnification for 5.56/.223 carbines from CQB snap shots to distance holds.
-
.223/5.56 BDC Green Chevron Reticle: Zero the illuminated chevron tip at 100 m; descending stadia provide calibrated bullet‑drop references for common 5.56 loads—fast center‑chevron for close work, precise holds to extended range.
-
Optimized Housing for Top Optics: Extended “battery saddle” design moves the accessory boss forward to better accommodate piggyback reflex optics (e.g., RMR) if added later.
-
Forged 7075‑T6 Aluminum Construction: Near‑indestructible ACOG chassis survives recoil from .22 LR through .50 BMG and harsh field abuse.
-
½ MOA External Adjusters: Positive, tactile clicks (2 clicks/inch @100 yd) simplify zeroing; ample elevation/windage travel for duty carbines.
-
Weather & Duty Ready: Waterproof, fog‑proof (nitrogen‑purged), shock‑resistant; tested across extreme temperature and immersion conditions.
-
TA51 Flattop Picatinny Mount Included: Out‑of‑box compatibility with MIL‑STD‑1913 / AR‑15 flattop uppers.

Made in USA & Backed by Trijicon Warranty.
