The Badger Ordnance Dead Level:

The Dead Level is the most simple and accurate way to level your scopes reticle for maximum performance at extended ranges. You simply attach you scope and rings to the Dead Level, then level the device with the precision thumbscrews to center up the bulls-eye level. By looking out a door or window to the edge of a building to a level line or a plumb bob, you align the cross hairs, tighten the ring caps and check it one final time. Finish is our standard Black hardcoat anodized Aluminum.

P/N is 200-50.

And, NO!! The scope is not included.
