Well I just took removed the stock and bolt from my rifle. I would say this had not been taken apart since it was new. The chamber was really dirty, I cleaned it the best I could, and unfired ammo was still sticking in chamber, not as bad but still sticking. Looks like I'm going to have to find a chamber polisher and shine her up. Any body know where I can buy one? Found the markings TC-10 stamped on the receiver and butt end of the wood, not sure yet what that means. Thanks to all of you for your help,
