So I dusted this scope off and put it on a db10 (large frame AR)
I've been trying to find ammunition that it likes, and shrinking my group sizes by improving my fundamentals.
I haven't gotten better than about two moa and this rifle should be able to do much better.
I did all that range work on 15x, I was just playing around with the rifle doing some dry firing on the lowest power 3x and noticed this black semicircle in the bottom of my scope.
I tried looking through the eyepiece at different angles thinking maybe my alignment was off or something but with my eye and my cell phone I can't seem to find a solution.
I did the best I could with my pictures so you can sort of see it, and then there is another picture on 15x where you can see that the scope is clear as it should be.
Should I send this scope into vortex or am I such a dumbass that I'm doing something wrong?
I don't have a rifle that shoots well enough to really test this scope, because I can't get the ammo that my other rifle really likes anymore...
Thank you in advance.
