Many things can effect accuracy on a AR, can you mount the scope on the upper receiver picatinny rail without the riser?
This may take a few back and forth posts here.
i'm shooting from a bench rest. i used loaded rounds as well as factory winchester rounds. The bullets are going all over the place deviating by as much as 6 inches!
I 'm using a riser because i didn't want to take off my front sight because my sling is attached to it.
