The Trijicon ACOG 5.5x50 delivers exceptional long-range precision with its illuminated red chevron reticle specifically calibrated for .223/5.56 ammunition. This combat-proven optic combines tritium and fiber optic illumination to provide a clear sight picture in any lighting condition without batteries.
What Makes This Different
Unlike standard variable power scopes, the ACOG's fixed 5.5x magnification eliminates parallax and maintains zero through extreme conditions. The dual-illuminated reticle system automatically adjusts brightness based on ambient light, while the bullet drop compensator (BDC) provides holdover points out to 800 meters. The hardcoat anodized aluminum housing withstands impacts that would destroy conventional optics.
Key Features
- 5.5x50mm fixed magnification with 50mm objective lens for maximum light gathering
- Red chevron BDC reticle calibrated for 62-grain .223/5.56 NATO ammunition
- Dual-illuminated tritium and fiber optic system requires no batteries
- Hardcoat anodized aluminum construction rated for .50 BMG recoil
- Waterproof to 11 meters and fog-proof internal sealing
- TA51 mount compatible with MIL-STD-1913 Picatinny rails
- 9.9-degree field of view at 100 yards for rapid target acquisition
Field testing demonstrates consistent accuracy at extended ranges where iron sights become ineffective. The BDC reticle eliminates guesswork for shots beyond 300 yards, while the 5.5x magnification provides sufficient detail for positive target identification. Military and law enforcement units rely on this optic in desert, jungle, and urban environments where battery-powered optics fail.
