I Purchased a T/C Omega and there was a Nikon 3-9 x 40 prostaff scope mounted on it already. This scope was probably bore sighted at the gun smith. When I was going through the Instruction manual I noticed all the pictures show the scope with the adjustment nobs on the top and left side of the scope. My scope is mounted with the adjustment nobs on top and right side. When I took the nob covers off, the top has a U and D and the side nob has a R and L. This leads me to believe the scope is a quarter turn wrong. If this dosen't matter I'm fine with the way it is mounted. Can anyone give me a reason on why I would want to change the scope? If so do I need to put a level on the scope or should I take it somewhere to be done. I'm planning on sighting in this gun today or tomorrow. Thanks for all your help.

Your scope is mounted correctly. I don't recall any manufacturer with the windage knobs positioned on the left side.

The scope is mounted correctly, like Sniper said.

Thanks guys

Your scope is indeed mounted correctly. On some rifles with a very low mounted scope, I have mounted a scope the way your picture shows, but then the R-L knob becomes the UP-DOWN adjustment, and the U-D knob adjusts windage. The reason I've done this is to get the R-L adjustment knob out of the way of the ejection port on a bolt-action for easier loading/unloading.
