Guys, the picture was mine, not Turmoil_OZ's. I uploaded the pic to show that the barrel (crosshair) doesn't line up with the optics. Exactly as it shouldn't at such extreme close range.

My attached file shows why this might happen. The crosshair is on the wall, but when you swtich to optics, you gain an extra inch or two due to the lean and height the scope sits above the barrel.
