The Primary Arms Absolute Cowitness
Micro Dot Riser allows for an absolute cowitness on AR15 and similar platforms
when combined with any Primary Arms Micro Dot, as well as many other standard
Micro dot designs. When looking down the iron sights, the red dot will be
placed in the middle of the Micro dot’s scope tube. The light weight design,
constructed of anodized aluminum, is easy to install. Primary Arms holds a 3-year
warranty on this product.
