When I first got mine, I couldn't even open the barrel because it seemed that the oil has formed a glue-like bond, until after using the floor, it finally opened. It had a LOT of oil in the breech, and theres no doubt that it got into the spring chamber. And BTW, I also saw smoke when I opened the barrel, from the breech. It had a heavy sharp smell, I dunno if thats oil or whatever. So I dunno why it had so much oil, but after detonating 5 times in a row... I said, that's it. I called Daisy, and they said that it's probably the oil but I should return it just to be safe. So I said, hold on a minute, don't i have a warranty here? she said yes, but we are in the process of relocating our business, so that it might get lost in all the rummaging, and I might never see it again. Some warranty. But then again, I ended up with my Viper, which hasn't ever had smoke come out of muzzle when fired
