i was issued a couple otis kits while i was overseas, i think they're OK but they could use improvement. i do like the cable so you can go breach-to-muzzle. basically a bore snake with attachments. CLP does work beautifully for breaking up carbon and lead deposits as well as penetrating the pores in the steel to help keep it lubricated the stuff even removes rust! personally i cannot stand the stuff, but that's just my unfounded opinion .
