I'm thinking, that Barrel, would be on its way back to Master. I'm sure they were proud of it, when you paid for it, but don't think they would be proud of that specimen. As others have said, its either, flawed machining, and cleaning, and or materials, or a combo of BOTH. Nice pic by the way, and for a nice price too. But also as said, the pix can keep you crazy, trying to figure it out. The Lilja, video said it all. I'd ship it. It's always gonna be on your mind.
