I very recently picked up an early TEC-9 (yeah, I know, junk kind of but still interesting) and it really needs a deep cleaning.
When I got it the bolt was stuck about 1/2" from the closed position and it was jammed solid. After some soaking in SeaFoam and some persuasion with a mallet I finally got the bolt out and it was really stuck in the tube with 40-year old solidified oil/grease and a little rust. The trigger group and mag catch were all similarly afflicted.
I've managed to clean all those assemblies but the extractor set screw is just not ready to give. I've soaked it; no joy. I've tried a small butane torch to heat the bolt, let it cool and try again; no joy.
Right now it's in my freezer and I'll give that a go tomorrow.
I even have a ratchet driver and 1/8" bit and it did nothing.
I'll probably give up and test it and hope it works, but given what I've discovered I suspect the extractor slot is full of garbage.
So, any ideas?
