Adapted from military applications, U.S. Forces have enhanced the Trijicon ACOG scope by integrating a small red dot sight on top for close quarters missions. Trijicon has now developed a similar model for civilian use, the TA31-D-100570. The primary Trijicon scope features a dual-illuminated reticle utilizing fiber optics and tritium, ensuring a bright aiming point under any lighting conditions. The ranging reticle facilitates bullet drop compensation up to 800 m without requiring manual adjustments. Positioned on top is a Trijicon RMR type-2, equipped with a 3.25 MOA aiming dot.

• ACOG models typically operate without batteries, utilizing a tritium/fiber optic illuminated reticle that self-adjusts brightness according to ambient light conditions
• Certain ACOG models feature a user-adjustable brightness setting, powered by a single AA battery, allowing for precise control of illumination levels
• The 3.5x35 LED and 4x32 LED models feature six customizable brightness levels, allowing users to adjust illumination to their specific needs
• The fixed-power design minimizes moving parts, resulting in a highly durable and nearly indestructible sighting system
• The Trijicon Bindon Aiming Concept (BAC) feature enhances situational awareness by enabling "both eyes open" shooting for improved target acquisition
• The high-quality glass and multi-coated lenses enhance light-gathering capabilities, providing a clear field of view with zero distortion
• ACOG models predominantly incorporate a bullet drop compensating and target-ranging reticle, facilitating precise aiming and enhancing target acquisition accuracy
• The ACOG is the most extensively utilized magnified optic in combat scenarios, surpassing all other similar devices in terms of deployment and usage
• Demonstrated to endure recoil from .22LR - .50 BMG calibers, this product consistently meets USA Military drop test standards
• Boasting superior waterproof capabilities, this product surpasses military standards, ensuring exceptional protection against water ingress
