The Trijicon ACOG 4×32 A4 USMC RCO (Rifle Combat Optic) delivers a fixed 4x magnification, optimized for rapid target engagement across varied operational distances. Engineered for exceptional durability and battlefield reliability, this optic integrates a forged 7075-T6 aircraft-grade aluminum alloy housing, providing robust resistance to impact, recoil, and environmental stressors.
Key Features
Fixed 4x Magnification
This optic provides a consistent, fixed 4x magnification, ensuring a stable and repeatable sight picture. This configuration is specifically designed for effective mid-range target identification and engagement, balancing field of view with necessary target enlargement without the complexities or potential failure points inherent in variable power systems.
32mm Objective Lens
The 32mm objective lens diameter is meticulously chosen to provide a balanced field of view, facilitating situational awareness, while efficiently collecting ambient light. This design ensures adequate brightness for target identification across diverse lighting conditions, contributing to the optic’s utility in dynamic environments.
Red Chevron Reticle
The integrated Red Chevron reticle is engineered for intuitive and rapid target acquisition. Its design supports precise aiming while drawing the eye quickly to the point of aim, mitigating time on target. This reticle is highly effective for both static and moving targets within its operational parameters.
Dual-Illumination System
The ACOG 4×32 RCO incorporates a passive, dual-illumination system. A self-luminous tritium phosphor lamp provides reliable illumination in low-light and no-light conditions, while an advanced fiber optic collector harnesses ambient light during daylight hours. This critical system operates entirely without batteries, ensuring continuous reticle visibility and maintaining operational readiness regardless of power source availability. This design choice significantly enhances the optic’s reliability in critical situations.
Forged Aluminum Housing
Constructed from a forged 7075-T6 aircraft-grade aluminum alloy, the ACOG’s housing is designed for extreme resilience. This robust material and manufacturing process deliver exceptional resistance to shock, abrasion, and extreme environmental factors, affirming its reputation as a dependable choice for precision and combat rifles.
