Makes a nice wall hanger - Barska Electro Sight Multi Reticle Red Dot Sight AC10632

Bought this sight not even 24 hours ago,I threw it on my ar15 300 black out and i completely regret buying it. Zerod the sight yesterday and today about 5 hours ago and went to the range and shot maybe 5 rounds and noticed it wasn't lined up with my barrel and I was hitting way left, so I did a quick "zero" if you could call it that with my pop up sights and Rezerod thinking maybe I moved it handling the sight, took a couple more shots and same story so I zerod it again and just watched the cross move about a quarter inch (on the glass itself) after every shot and did this until the cross was completely out of my shot picture. Well now back at how monkeying around with it I have found out its not the equipment that holds the zero being defective its the projector itself because as of now the sight is pegged to the right and down and my cross is barely visible on the bottom right corner. So if you plan on getting a sight save up get something decent, luckily I had my pop up sights and I didn't lose a days shooting because my optic failed.
