I’m having an issue with the “bolt stop” not catching the bolt. I tried to download the pdf that Timney has on the website but that’s not working. The instructions on the website say to file the top of the trigger, but I am not able to visualize how this modification is going to help any. That’s why I was hoping the pdf would show something that I’m not gathering. I tried to find something on YouTube but can’t find it. Let me know if anybody has any insight or I’ll call Timney Wednesday.
