Made one of these for a PH sported receiver, out of some aluminum angle. Mounted a flat bottomed Weaver base on top. Drilled and tapped the holes for the Weaver base using my Forster jig, so the holes were lined up properly. Don't know why a mount like the one Woodchopper has illustrated couldn't be made, mounting the same way. Aluminum angle is a lot easier to work than steel, and is plenty strong enough. I have a Cad Technik on one of my rifles. Very nicely made, and the scope can be detached if desired, leaving the base on the rifle.
