Carbon fiber is well-suited to the tough tasks assigned to cleaning rods. It combines the best features of stainless steel and coated cleaning rods, then adds valuable properties of its own. Carbon fiber can't scratch your bore like stainless steel, and they won't embed like coated rods. Plus, Carbon Fiber rods can be bent to an extreme degree and return to their original straightness. Feature an ergonomically designed handle that spins on two sets of ball bearings - the result is a cleaning rod that smoothly follows the rifling both pushing and pulling, even while under pressure. The "shank-through" construction also allows the user to apply "reasonable" hammer blows to the end of the cleaning rod to get a tight patch through a bore.
