I agree alleyyooper, the bolt is something I think people overlook. The guyI got mine from kept the gun spotless except for the bolt. I don't know if he didn't realize it got that dirty or just didn't know how to take it down.. Nonetheless, it was quite dirty. That take down tool is a gift from heaven. The whole, vice and a coin thing is a joke after using one of the tools.

A stronger spring couldn't hurt either. I changed out the factory one in mine to the Cabela's one. I don't know how stout it is though.
