For general barrel/bore cleaning, I suggest buying some high quality bore cleaners like Hoppes #9 or Sweets or 7.62 or Butch's Bore Solvent.
As for Break-Free, it's ok as a CLP, but you may want to order some more high tech CLPs like Weaponshield, Eezox, Gunzilla or Mpro7's LPX.
A Bore-Snake Viper can aid your barrel-bore cleaning too.
