I bought some really stiff pipe cleaners at my local indoor range/gun shop. Should probably do the trick. Unfortunately for me I am AK-less for now. Sold a Norinco I had for a tidy profit, regretted it ever since. Now my wife wants me to wait for another purchase. Anyway, you will have to check for yourself if it works. From what I remember, I could get the Army issued pipe cleaners to work on my Norinco a few years back when I was still in the Army.
