I've had this M6 Scout .22LR/.410 for quite a few years now. I haven't shot it much, but when I did, it seemed to be all over the place with .22's, the 410 part seemed to hit well enough. I never really took the time to work with it. The other day, while cleaning it, I found that the rear sight is free to slide back and forth for adjustment, it has a spring-loaded ball arrangement under it to put some tension on it, but it slides easily. There's a threaded hole in the sight, it looks to me like there should be a set screw in there to lock the sight in place. There is no screw in there. The hole seems to be the size of a #8 machine screw, but a #8-32 won't screw in. Using a #4-36 tap as a thread gauge seems to indicate that the threads are 36TPI.
My questions: Am I correct that there should be a set screw in there? Am I correct in thinking it is #8-36, does that exist at all, or is it something metric? And, the most important question of all, Where can I get one? Thanks all for your help. BW
