My gas tubes okay. The corrosion on it and the piston came off.
I spray remmington bright bore into it, pull a bore snake through it, and cram paper towel into the large end, twist it and pull it back out, then spray oil in it. The piston gets bright bore, then wiped off with paper towel, then wiped down with oil.
Is that a decent process?
I don't want to punch the pin out for fear I might wreck something or not be able to get it back, so I just spray oil on the underneath of the tube and hope it gets on the metal under the wood.
