Range Fun - Update

I spoke to my boss today about the AR-15 I sighted in for him yesterday, and through that conversation the mystery was solved as to why the windage was full right. The scope is a UTG Bugbuster and it has a lighted reticle for which he believed there was a spare battery. Instead of screwing off the cover on the left side of the scope he turned the windage knob full CCW on the right side of the scope.

At least I know now why it was so far off.
