I apologize if I haven't gotten approval for this post (I read the approval sticky, but I couldn't figure out how to get approval). So here's my question: I have a 1893 marlin in 32 special caliber. The trigger screw is REALLY frozen. I've tried tapping on it under tension with no luck. I've soaked it in Kroil for several days. My feeling is that it was torqued in way too tight however long ago. I definitely don't want to strip the head or break the bolt. Is there a manual impact screwdriver manufactured that you can strike that will perhaps loosen this sucker? Any other suggestions are welcome.
