How do you get something into the gas ports to get the crud out?

I don't see how to get access to the gas ports that come out of the bottom of the barrel.

Thanks,

Doc

Pipe cleaner, pick, punch or any wire that has some flex.

Drill bit, or you can buy a special brush. Also a bass guitar string cut into 6” lengths works.
There is only one port that goes through to the barrel, look into the housing that holds the gas piston.

Pipe cleaner is what I use. DO it while having the barrel off. Remove the gas piston. It's a little easier if you have sprayed it down first while you cleaned everything else. Gives the penetrant a little time to soften up the carbon.

Drill bit by hand.
