Leupold's ACOG Killer
The Leupold Mark 4 HAMR was an innovative prism optic designed to compete with the Trijicon ACOG, featuring battery-powered illumination and integrated red dot mounting. Despite its advanced features for the time, it was discontinued due to high cost and Trijicon's rapid LED-powered ACOG release. The HAMR offered user-adjustable illumination and a more adaptable diopter, but its market success was limited.
