i would just forget about them Slab...standard cleaning methods are perfectly fine... solvents and greases are the only thing that has changed pretty much...

also, that video is a stupid way of cleaning your rifle.. why would you pull all the "loose" junk and crud down into the action? if anything you would pull it out of the barrel from inside the action... problem with that, is all the gunk that accumulates on those stupid things, ends up where the bullet enters the barrel...

bolt action rifles are even easier to clean...

bore snakes always have grime and crud in them after the first use... clean wire and fresh rags are always clean...

just my OP...
