After losing aprroximately 8 detent ball bearings, I finally succeeded installing the rear sight elevation screw with BOTH balls in place. The only way I finally got them in was using my finger to push in the last ball. Screwdrivers, punches, cut off toothpicks, nothing worked so finally using my index finger i was able to get it in. The sight works fine now and Im ready to go sight it in. Wow what a job I hope I NEVER have to do that again. But it was quite an experience. I dont think Id be too good at fixing watches!
Compared to this, working on the bolt timing, is easy!
