Overview
The Trijicon ACOG 4x32mm optic is a purpose-built, self-illuminated fixed power sighting solution engineered for consistent performance with .223/5.56 caliber weapon systems. Its internally-adjustable optical system, coupled with a tritium-powered green crosshair Ballistic Drop Compensator (BDC) reticle, provides consistent aiming points across varied lighting conditions without reliance on batteries. This design enables sustained target focus in low light or bright sun.
Engineered for durability and practical application, this ACOG model integrates with M16-pattern rifles, providing a clear sight picture and ranging capabilities. As a critical piece of tactical optics, it facilitates rapid and accurate target acquisition across varying distances. The design prioritizes performance, making it a suitable firearm accessory for a precision rifle deployed in competitive, hunting, or personal defense roles. Its fixed magnification and optical clarity are beneficial for rapid target engagement and extended observation, whether in the field or at the shooting range.
The ACOG is constructed to withstand demanding environments, featuring a black hardcoat anodized finish that resists wear and mitigates glare. It delivers a direct enhancement to a rifle’s aiming potential.
Key Features
Self-Illuminated Reticle
The green crosshair BDC reticle is self-illuminated via a tritium/fiber optic system, eliminating the need for batteries. This ensures continuous reticle visibility and consistent aiming in all lighting conditions, optimizing performance in dynamic environments.
Fixed 4x Magnification
A fixed 4x magnification provides a consistent field of view, enhancing target identification and engagement at relevant distances without the complexity of variable power adjustments. The 32mm objective lens ensures adequate light transmission for a clear sight picture.
Robust Construction
Constructed from high-grade materials and finished with a black hardcoat anodization, the ACOG is engineered for extreme durability and resistance to wear, corrosion, and environmental stressors inherent to rigorous field use. The internally-adjustable optical system maintains zero under recoil and impact.
Optimized for .223/5.56 Caliber
The integrated Ballistic Drop Compensator (BDC) reticle is precisely calibrated for .223/5.56 ammunition, providing accurate holdover points for rapid engagement at various ranges.
Integrated Mounting Solution
Designed for direct integration with M16-pattern flattop receivers, ensuring a secure and repeatable mount. The included thumbscrew flattop adapter facilitates straightforward installation.
