That didn't show the handguard removal, but did have the right effect of getting rid of some of my fear of taking apart my weapon. After monkeying with it a bit more, I got it out without removal of the gas tube (still don't know how to do that, it's not like the video). FYI, the handguard was hanging up with friction right where that screw was, just plastic against metal and it took a little tugging on it to free it up. I'm cool now, thanks a bunch.
Great advice with the paste wax, she'll be right in no time.
