If you are perhaps thinking Carbon Fiber might, in some way, be less abrasive than steel or plastic coated steel or aluminum think again. I make knives as a hobby, using carbon fiber as bolster or handle material. The only way you can cut it is to use the same bandsaw I use to cut my blade steel...the carbon fiber will eat up a regular wood cutting blade...it can be tough stuff, and it will abrade the soft (in relative terms) barrel steel.
Glad you posted this. In the old days when I was in the machine shop daily the cutters were eaten up by the carbon fiber. We had to use Carbide cutters. If I used a carbon fiber rod, I would worry about barrel wear.
