How do you guys level scopes?

[Old Bob]

Anyone use the Arisaka Optic Levelor? A friend just texted me said this is the best thing since the invention of the AR-15. Thoughts?

Works OK if the bottom of the scope is absolutely flat. Not all scopes are flat even if they appear so. Also, you can't use it with some cantilever type scope mounts. They have to be flat too. With some scope/ring/base combos, there isn't enough room for the device to fit. I haven't been able to get a Leupold scope level with that device. It's a good idea & works when conditions are ideal.
