Bill, the video I posted in post 91 is the actual deal. It is that easy. I won't be using the patchworm with this gun. That's why I have been saying that I think the liner system is pretty neat, it is! And the liners, at least this particular liner, is one of the most accurate barrels I've ever used and absolutely the least slug picky I've even heard of. Of course, you know and I know that there have been plenty of bad liner stories, but mine isn't one of them. Knock wood. Additionally, I don't know if the glued on carbon fiber liner is needed because I didn't shoot the gun until it was on, but like I've said, if this gun shot this well for the first owner then I can't imagine why he sold it, unless he just got out of everything.
