OK SO I got a nifty Tipton gun vice for my birthday. I got out the AR the other night and my 6" torpedo level. I am lucky because my gas block is a railed version. I set the level on there and leveled the rifle and making sure it stayed level I tightened it down. I then placed the level on the top turret and seen that the scope was canted slightly (About 1/16 to 1/8") to the right. So I loosened the rings and set it level. WOW What a difference that made. Now my question is how do I do that on a bolt gun? I have no flat spot on the receiver to place a level not even a string level. Do I need to remove the scope completely and use the level on the bottom half of the rings? or on the mount? It is a Leupold one piece mount on one and 2 piece bases on another.
