It's okay. The sight base just moved because the blue Loctite didn't 'take'. Maybe it's too old. I just finished fixing it so I'll see how it holds up. I didn't use Loctite this time. I used a form of RTV silicone because I may want to shift or remove that sight at some future time. And I really cleaned and degreased the sight base and receiver dovetails, too. If it doesn't stick, I'll try something else. No big deal. It sure had me going at the range though.
