DougGuy, I knew someone would notice the uh, what looks like a crown. Glad it was you. It doesn't even conform to the un square badly sanded roller coaster looking muzzle. My 1990's camera needs replacing. I took over 200 pictures to get only a few good ones. If you look down the bore it's really easy to see the good side of the bore, and the non existent lands on the other. I'll post the best bad picture I could take. The lands are only about .0005 tall. You can barley get a tooth pick to snag on them.
Attachment 197318 I told you I need a new camera. I did ask customer service about getting my money back, and the place I purchased it. It will mean loosing hundreds of dollars. I am still thinking about it though because I haven't clicked the "set up the return" e-mail marlin sent me. I'm thinking I'd have to wait till they ran another batch of barrels.
