In advance of I went to the assortment, I tossed an HS509T to the AR 410 and did A fast zero with buckshot hundreds. I like these little optics on shotguns and use the circle and dot reticle. The circle is for buckshot, along with the dot is for slugs. https://trevorzmzmw.win-blog.com/23080711/charles-daly-410-ar-shotgun-options
