It's a bit harder than that (at least on the CX). The laser mount and
lens mount are 2 separate parts, one has a convex (spherical) face, the
other concabe. There are a couple of screws to lock them toeghter, but
you have enough movement to be able to direct the beam by shifting the
laser mount. And of course I had to do that.
But the complete assembly will come off and go back with no problems.

OK, but remind me if I don;t make a comment fairly soon...
