The Trijicon ACOG Riflescopes series represents a legendary class of fixed-magnification combat optics designed for reliability, speed, and precision under the most demanding field conditions. First introduced in 1987, ACOG has evolved into one of the most trusted riflescopes worldwide, adopted by military units, law-enforcement, and serious shooters for patrol carbines, combat rifles, and duty weapons.

Built from forged aluminum with fully sealed internals, ACOG scopes offer rugged durability, dependable zero retention, and optical clarity that excels from close-quarters to medium-range engagements. Whether used for duty, tactical work, or precision shooting, ACOG delivers consistent performance without reliance on batteries or external power sources.

Key Features

Fixed-Power, Combat-Proven Magnification
Available in fixed magnification levels from roughly 1.5× up to 6× (depending on the model), ACOG optics provide a balance of close-quarter responsiveness and extended-range precision.

Battery-Free Dual Illumination
Optical fiber and internal tritium illumination automatically adjust for ambient light — providing a clear, bright reticle in daylight, low-light, or night conditions without batteries.

Prismatic, Compact & Durable Design
Forged-aluminum housing, sealed construction, and shock-, fog-, and waterproof engineering ensure reliable operation under recoil, adverse weather, and harsh field conditions.

Bullet Drop Compensation (BDC) & Calibrated Reticles
Many ACOG reticles include ballistic drop compensation (BDC) and calibrated stadia for common service calibers — simplifying holdover for mid-range targets.

Wide Field of View & Fast Target Acquisition
Thanks to optimized glass, reticle design, and eye-relief choices, shooters get a generous field of view for quick target transitions — even in dynamic situations.

Proven Military Heritage
Originally fielded by U.S. military forces and adopted by Special Operations and Marine units, ACOG has decades of real-world combat validation under its belt.

Low Maintenance & Always-On Optic
With no batteries required and a rugged sealed design, ACOG scopes remain ready even after extended deployments, heavy recoil, or environmental stress.

Ideal for AR-Platform Rifles & Combat/Patrol Carbines
ACOG’s size, magnification, and ruggedness make it exceptionally suited for M4/M16-style rifles, PCCs, and tactical carbines where reliability and ease-of-use matter most.
