The Trijicon ACOG 4x32 is a rugged fixed-power optic built around a compact housing and battery-free dual-illumination system. This example uses fiber-optic illumination in daylight and tritium illumination in low-light conditions. Trijicon’s 4x32 RCO models were developed around military-style 5.56 platforms and are known for their durable construction, wide field of view, and Bindon Aiming Concept capability.

This optic is in very good condition, showing light cosmetic wear from normal mounting and use. It includes a Trijicon thumbscrew mount, an RCO-ARD anti-reflection device, and a KillFLASH honeycomb lens cover. The red fiber-optic illumination strip is intact and visible in the photographs.
