Trijicon ACOG 3.5x35 Red Donut BDC Reticle .223/5.56 Optic

The Trijicon ACOG 3.5x35mm delivers combat-proven magnified optics with tritium and fiber optic illumination that requires no batteries. This fixed-power scope provides consistent target acquisition in any lighting condition, from bright daylight to complete darkness.

What Makes This Different

Unlike variable power scopes that can fail under stress, the ACOG's fixed 3.5x magnification eliminates moving parts while maintaining a wide 28.9-foot field of view at 100 yards. The dual-illuminated reticle combines tritium for low-light conditions with fiber optics for bright environments, automatically adjusting brightness based on ambient light. The forged aluminum housing withstands impacts that would destroy conventional scopes, meeting military specifications for shock, vibration, and temperature extremes.

Key Features

• Dual-illuminated red donut reticle with tritium and fiber optic technology
• Bullet Drop Compensation (BDC) calibrated for .223 Remington and 5.56 NATO ammunition
• 3.5x fixed magnification with 35mm objective lens for optimal light transmission
• Forged aluminum construction with hardcoat anodized finish resists corrosion
• Waterproof to 11 meters and fog-proof with dry nitrogen purging
• Mounts directly to MIL-STD-1913 Picatinny rails without additional hardware
• Eye relief of 1.5 inches accommodates protective eyewear and tactical helmets

The ACOG excels in rapid target engagement scenarios where battery failure could prove catastrophic. Law enforcement and military personnel rely on its instant-on capability for close to medium-range engagements out to 600 meters. The BDC reticle provides holdover points for various distances, eliminating guesswork in field conditions. Temperature extremes from -40°F to 160°F won't affect zero retention or reticle illumination.
