Well basically it took 80 posts to figure out that by your own admission you had a very dirty gas piston, you did not clean or lubricate you rifle properly and you had the wrong spring. And you think I'm irritating ?? No wonder you are closing in on 5000 posts. Unbelievable.
I appollogize for being irritating to all the other genuinely helpfull posters on this thread. I also hope all the chrome lining peels off my barrel so I can have the DOC fix me up with a new one ! A man's gotta do what a man's gotta do.
