Fx no limit and other adjustment mounts can cost you $69 to 100 plus shipping fees. But I found these cheap adjustment mounts on eBay for only $9.99 each, with free shipping and no tax. They work great and feel solid. You adjust by turning a dial and use set screws to lock it in place. The will fit both 30mm or 1" tube. So don't matter what scope you have, it will fit it.

Those who are worried they will cause damage to scope cause it won't tilt. You can take 2 pins out and it will tilt enough that it will not damage scope. Watch video to see how to take pins out. Skip to 4:00 to see how to remove pins for tilt.
