I generally buy the parts separately. Where I live Outers and Kleenbore are available in most Gun Stores so I just go with those. I like the Outers brushes since they are a tad more snug in the bore. Same with their jags.
For cleaners I use Mpro 7 with a bit a shooter's choice copper fouling remover when necessary. I use Mpro7 patches for the bore but stick to cheaper brands to wipe the rest of the gun.
Q-tips are also essential.
I would get the Kleenbore plastic coated rod. If you also like the outers brush there are rod adapters available.
I like having two rods so I don't have to change accessories back and forth.
