there is a little bit of markings when the smear test is done. the madbull TB is still clean. The guys last night can tell you that I went through plenty of round too.
I do use a mix of tracers and regulars (bastards/metal techs) though so the regulars might be helping keep the barrel clean.
I will confirm this sometime the next week or two when I break the AK down to install a Modify s90 spring.
