The Aimpoint Micro S-1 was designed specifically for use of shotguns. The innovative carbon fiber reinforced mounting system positions the optic on the lowest possible optical axis - without adding unnecessary weight. The Micro S-1 sight attaches directly to the shotgun at any point along the ventilated rib, and interchangeable adapter plates are included to accommodate most popular shotgun rib sizes. The Micro S-1 greatly enhances hit percentage for hunters, as well as on the sporting clays course. It provides a compact, low-profile optic for shotgun hunters. The big, bright 6 MOA red dot provides an optimal combination of target acquisition speed and visibility.
