Almost no kit out there specifically addresses cleaning of the action. The only thing you need for that is solvent, an AP brush and towel to wipe it off afterward. If you have a weapon with odd type chamber, ARs specifically, than you somewhat need a brush to clean that also. I guess my whole point is the Otis kits are built around one thing do one thing clean the bore. Which, it does to an acceptable level, but I wouldn't say too much better or worse than most kits out there. If you like to have 1 kit that does it all than, it may be ideal for you. I am personally of the opinion that they fall much into the same category as BHI, they make an acceptable product and than market the hell out of it, because of the marketing it tends to be what most guys get or most supply officers order.
