What is the reticle design and calibration of the Trijicon ACOG?

This ACOG features a chevron reticle designed to be zeroed at 100 meters using the tip. The hash marks below the chevron are calibrated to compensate for the bullet drop of 5.56 NATO rounds out to approximately 800 meters.

What are the benefits of Target Nation's 3D targets?

Target Nation's 3D targets provide a third dimension to shooting practice, enhancing understanding of how target facing affects shot placement. They are easy to assemble from flat cardboard and can accommodate standard paper scoring targets.
