They answered me pretty quick a few hours on my question about replacing the silver bolt knob with the stainless one on the trigger guard package.Has anyone ever had to get ahold of these guys with a problem? I have a dbm from them that was purchased around 2010, never installed, that shipped with an out of spec lever. It was a known issue at the time. I forgot all about it until I saw this thread. I've sent an email but have not heard back.
