UtahLefty: so this thread is definitely a bit old, but I'm having the exact problem you described (about the sear slipping and causing misfiring) on my .22 A-bolt. How did you get that problem resolved when you were dealing with it? My gun is flawlessly clean, no rust etc. Taking it apart I can't *find* anything that looks like it's not working, but that cocking indicator definitely slips down if I half-uncock and then recock the bolt.
