The HexCap™ is a ruggedly simple, snap-fit Anti-Reflection Device (ARD) that installs securely in seconds to your red dot sight with no additional hardware.  We designed the HexCap™ to be as low profile as possible while maintaining durability for use in the field. Its hexagonal lattice allows you to see through the optic with minimal obstruction while eliminating downrange reflections.  Anti-Reflection Devices are nothing new, but there simply aren't good options for many of the red dots on the market today – especially with the rise in popularity of top-mounted and offset red dot sights. Our goal with HexCap™ is to solve that problem. Also compatible with EOTech 518
