When loosening the knob it seems to have something stopping it. For removal, do I just keep turning it to the left?
I just grabbed the sight, and twisted the locknut right off (I used pliers on the nut itself--forgot to add); it takes some force, but not a whole lot, and the threads weren't damaged at all. Once the locknut's off, install the sight with the replacement nut. I think it's an M5 (can't remember, exactly), but you can always take the sight into the store with you to make sure you get one that fits. Once the sight is installed, you just cut off the excess threads on the mounting bolt, and reblue. If you can, get a blued nut for the replacement. If you can't find blued nuts, you can carefully grind off the plating to blue it.
I think Quib and myself had the same idea at about the same time, because when I originally posted about mine, he had just gotten through doing his, also.
