The ACOGs combine traditional, precise distance marksmanship with close-in aiming speed. Although the ACOGs have many features which are very advantageous for military use, they were developed by Trijicon without government funding.

Designed for use with the M16 family, every feature of its mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions -- without failure-prone batteries.

ACOG 4x32 Scope with Red Chevron BAC Flattop Reticle - includes Flat Top Adapter. The chevron reticle is designed to be zeroed using the tip at 100 meters. The width of the chevron at the base is 5.53 MOA which is 19" at 300 meters.

This allows range estimation for silhouette targets.Features Dual Illumination (Fiber Optic provides daylight illumination and tritium illuminates reticle at night). The ranging reticle is calibrated for 5.56mm (.223 cal) flat-top rifles out to 800 meters. Includes Flat Top Adapter (TA51).
