Trijicon ACOG 4×32 LED Riflescope .223/5.56 BDC Red Crosshair Reticle
Features
-
User‑Selectable LED Illumination (AA Powered): 6 brightness settings with an “off” detent between each for fast return to preferred intensity; uses a standard AA battery (alkaline or lithium).
-
Extended Battery Life: 12,000+ continuous hours on the mid (#4) setting at ~21 °C; lithium cells improve cold‑weather reliability and runtime.
-
Night‑Vision Friendly Low Settings: Lower output levels are suitable for use in front of image‑intensified NV devices to reduce reticle bloom.
-
4× Fixed ACOG Optical System: Rugged prism design provides a bright, flat image and rapid target acquisition from CQB distances out to the effective range of 5.56 carbines.
-
.223/5.56 BDC Red Crosshair Reticle: Zero the crosshair intersection at 100 m; descending stadia deliver calibrated bullet‑drop references for common 5.56/.223 loads—clean, uncluttered aiming to distance.
-
LED Battery Saddle Housing: Side‑mounted battery compartment improves handling and leaves clearance to add a piggyback reflex optic (e.g., RMR®) if desired.
-
Forged 7075‑T6 Aluminum Construction: Field‑hard duty body is shock, recoil, and environment resistant.
-
½ MOA External Adjusters: Positive tactile clicks (≈2 clicks/inch @100 yd) simplify zeroing and in‑field corrections.
-
Weather & Duty Ready: Sealed, nitrogen‑purged, waterproof, and fog‑resistant for harsh environments.
-
TA51 Flattop Picatinny Mount Included: Out‑of‑box compatibility with MIL‑STD‑1913 / AR‑15 flattop receivers.
-
Made in USA & Backed by Trijicon Warranty.
