I was going to recommend the OTIS cleaning kit but the kit you're looking at appears to be based on the exact same method. The only thing you can't do with this type of system is scrub back and forth in the barrel. That can lead to longer cleanings. Having said that, it would be quicker to buy a bore guide and use a one piece coated rod. For portability purposes, what you're looking at will take care of the job and then some.
