I'll get him over here and we'll try that. Saw a video online how to take it all the way apart, and it doesn't look bad at all.
Oh, so it's
never been fully disassembled and cleaned?? I was under the impression it had been done from the OP..
Two things: you WILL need a bit of heat to break the factory red lock-tite on the action tube.. Second, when you get it apart, also clean the inside of the action tube and inspect/lube and/or replace the O-ring that's there..
Heat is applied to the lower 1/2" of the action tube just ahead of the receiver.. Done once, you won't have to do that again..
