Alternate zero and using the laser alignment jig instructable.

Thanks for posting this guide Mark. It covers something that I kind of glossed over in the laser sight demo video but get a lot of questions about.

I'm glad you think it will be useful, if there is anything you think needs to be clarified feel free to point it out. That is what I like about Instructables is that they are editable and can continue to get better even after publishing.
