Updating my last review - NcSTAR MARK III Gen3 Tactical 3-9x40 Rifle Scope

I left a review on this after shooting it just once or twice. After I recently purchased a bipod, though, it became obvious this scope is not accurate at all. I can set the rifle perfectly steady on the bipod and, if I move my eye around behind the scope, I can see the crosshairs move around on the target up to 2 inches in either direction. Hopefully that explains why my groups are 5 or 6 inches wide at 50 yards. Also, the target just isn't nearly as clear & crisp as the $100 Sig Sauer scope on my other rifle. Also, my Sig Sauer scope's crosshairs don't move around at all when I move my eye around behind it. I'll be buying a different scope and throwing this one away.
