Do not buy one of those kits with the multi piece aluminum cleaning rod.The rods flex and rub on the rifling which isn't a good thing.Buy a good quality coated steel rod like a dewey and buy a .270 bronze brush and a matching jag.Then buy a bore guide,some properly sized cotton patches,a powder solvent like shooters choice,a copper solvent like barnes cr-10 and a good gun oil like the one made by g-96.That will include all the components that you need to properly clean your gun without damaging the barrel.
