Trijicon ACOG ECOS 4x32 .223 BDC Amber Crosshair FDE Combo

The Trijicon ACOG ECOS 4x32 delivers precision optics with dual illumination technology for tactical and sporting applications. This fixed-power scope combines tritium and fiber optic illumination to maintain reticle visibility across all lighting conditions without batteries.

What Makes This Different

Unlike battery-dependent optics, the ACOG ECOS uses Trijicon's proven dual-illumination system that automatically adjusts brightness based on ambient light. The amber crosshair reticle provides superior contrast against varied backgrounds compared to standard red reticles. Built on Trijicon's combat-proven ACOG platform, this scope maintains zero through temperature extremes and heavy recoil that would compromise lesser optics.

Key Features

• 4x32mm fixed magnification with .223 bullet drop compensator reticle
• Dual illumination system combines tritium and fiber optics for 15-year lifespan
• Flat Dark Earth finish matches modern tactical rifle systems
• Forged aluminum housing rated for .50 caliber recoil forces
• TA51 mount compatible with MIL-STD-1913 Picatinny rails
• Waterproof to 11 meters with nitrogen-purged fog resistance

Field performance centers on the ballistically-matched reticle that provides holdover points for .223/5.56 ammunition from 100 to 800 meters. The 4x magnification balances target identification with situational awareness for patrol rifles, designated marksman roles, and precision hunting applications. Temperature stability from -40°F to +160°F ensures consistent point of impact across seasonal conditions.
