All Carbon Fiber barrels have a $100 upcharge due to the custom tooling and workholding involved over a standard steel barrel unless the barrel is supplied by us. We work with Proof to have barrels specifically made for our machines and systems. Any questions contact us.
With this service, a barrel blank (yours or ours) will be custom threaded to fit any receiver, chambered in your specified caliber, and the muzzle threaded. All muzzle threads are cut based off of bore cylindricity to less than .0003” TIR.
