I bought my 580 Mini about 2 1/2 years ago. Cleaned it new, and I've ran about 350 rounds through it. I decided to clean it today, and I have some questions.
-What do I need to clean the chamber? I bought a .38-.357 brush that I thought would be close, and it isn't right. -How do you take out the gas bushing to clean it, and how do you clean the gas ports in the barrel?
-Should the gas bushing be loose in it's mounting? Apparently it leaks for all of the fouling found on the inside of the gas block.
-When I squirted carburetor cleaner in the barrel, it leaked around the base of the gas bushing and out of the gas block and ran down the outside of the barrel. Should it be doing that?

Other than those things it went ok, except for it being a bitch to get the bolt back in the reciever. Any thoughts/comments/advice from those of you with a lot more Mini experience than me would be greatly appreciated.

I would recommend getting an M16 chamber brush for it. You should be able to find a complete M 16 ceaning kit at a military surplus dealer or in shotgun news ads (or
