I've got a rivet on my Century M70B1 that needs some work.  The monkeys at Century must have taken a break just as this one needed to be squeezed.  

Anyone in Renton area have a AK rivet tool I could use?

What does the rivet look like right now?

In many cases you can just further squeeze the rivet and go on about your business, but it depends on which one it is. If it's one of the forward rivets hidden on the inside by the barrel, there isn't much you can do other than pound it in from the outside, and it will likely pop out again - the barrel really needs to be pressed out to properly fix those.

A friend of mine has some of my bolt cutter jaws right now, would be happy to help you out whenever he's done with them, but no idea when that would be.

These rivets are at the mag well, and are accessible on both sides.
