http://www.midwesthuntersoutlet.com/item.aspx?PID=508365&w=PQ+JDyOLrQE= Anyone have any experience with these? I can't find a review on this anywhere. I saw on random forum a guy mounted on on a shotgun (20ga I believe), and said it felt well made, but there was no post about how it held up. Any info on these? Think it'll hold zero on a .223, or should I just wait and get the EoTech?
