The Aimpoint Micro H-1 ACET(Advanced Circuit Efficiency Technology) was designed with the hunter in mind. These sights are the lightest red dot sights tough enough to carry the Aimpoint name. Small enough to be used anywhere you could put iron sights, these sights can be used on any type of firearm or archery equipment (Ideal for rifles, carbines, shotguns,sub-machineguns, and handguns) A lightweight rifle with an H-1 Micro mounted on it remains a lightweight rifle! A hunting revolver with an H-1 Micro installed remains as easy to carry as with iron sights and is much faster to aim. On a bow, the parallax free H-1 Micro eliminates the need for a peep, allowing you to shoot accurately in lower light.
