    Great product

    Great buy for anyone wanting to easily aligne gas block. Marks on Genie do wash off easily. I saw on another review that it doesn't work well with adjustable gas blocks with gas screw protruding from front of gas block. I just set my marks at the end of this screw and it was all aligned correctly. Just waiting for the .875 and .936 sizes.
