Eef! No comment. :s
I don't use mine often enough to poof parts.
Someone else will have to comment on that; but I will say that the bolt was a subject that was brought up very early in the Hammer's introduction. Assurance was made and backed by those that have used previous Hammers with the same type of hard anno'd aluminum bolts that are still in service after many years.
As a correction to a comment I made above; the aluminum tape was added to the top side of the "port" on the hammer that extends into the bolt. It took two pieces of the tape to remove the kinking. I tried three; but it sheared and balled up the third piece.
