hi there, just needing to know is there a difference in the combat barrels vs the standard, i was told by a friend who knows nortons that the combat barrels were factory skimmed which made the compression higher, but have been told (in the for sale section) the barrels were the same and only the heads were skimmed/shaved at factory to increase compression, can anyone shed some light thanks
