Just get this!!! - Arisaka Defense Small Optic Levelers

If you're in the process of mounting a scope and are looking for the easiest possible way to level it out then this little gadget is an absolute must-have! Don't even bother screwing around with bubble levels and other devices that take more time and cause more headache. Mount the scope in the rings and leave it loose enough to swivel the scope, stick this bad boy under the flat spot on the bottom of the scope, swivel until it lays flat on the arisaka piece and boom you're done! Much more precise than bubble levels and so much easier. This is a no brainer folks
