The Trijicon ACOG (Advanced Combat Optical Gunsight) 3×30, calibrated for .223 Rem / 5.56 NATO, is engineered for uncompromising performance in medium-distance engagements. Adopted by the U.S. Marine Corps and U.S. Special Operations Forces, this optic delivers consistent hit potential across all lighting conditions, defined by its formidable durability and reliability in the most demanding operational environments.
Key Features
Optical Performance and Reticle
The ACOG 3×30 features a fixed 3x magnification and a 30mm objective lens, providing a clear, bright image with a generous field of view for enhanced situational awareness. Its specifically calibrated Red Chevron reticle offers bullet drop compensation (BDC) for .223 Rem / 5.56 NATO ammunition, facilitating rapid, precise engagements at various ranges. The etched-glass reticle maintains integrity regardless of illumination status.
Construction and Durability
Constructed from a single piece of forged 7075-T6 aircraft-grade aluminum alloy, the ACOG’s housing is designed for extreme resilience. This robust chassis ensures the optic is waterproof to 100 meters (330 feet), fogproof, and shockproof, maintaining zero under repeated recoil and harsh field use. The integrated mount interface provides a secure, low-profile attachment to MIL-STD-1913 Picatinny rails.
Illumination System
The ACOG 3×30 utilizes a tritium and fiber optic dual-illumination system, eliminating the need for batteries. Fiber optics automatically adjust reticle brightness in daylight, while the tritium phosphor lamp ensures reticle illumination in low-light conditions, providing a consistently visible aiming point without manual adjustment or power source dependence.
Integration and Utility
Designed for rapid target acquisition, the ACOG’s fixed magnification and generous eye relief optimize its utility for combat and competitive applications where speed and precision are critical. Its proven track record across over one million units in the field affirms its status as a high-performance, dependable optical system.
