Eotech Holosights are currently in use by our armed forces overseas, and are relied on in every adverse condition imaginable. Eotech sights mount on military weapons as well as sporting firearms such as shotguns, rifles and pistols for competition and hunting. Battery options for the Eotech HWS include “AA” and “N” sizes. Eotech scopes are rugged and reliable and include night vision compatible models such as the EOTech 551, EOTech 552, and the EOTech 553. The EOTech 511 and EOTech 512 do not have the night vision option. EOTech military red dot sights are as durable and reliable as a red dot sight can be.
