Very well machined, very poorly packaged and/or stored - Centurion Arms MK 12 Threaded Rifle Barrel

The machining and finish on these barrels is excellent. Had they been packaged and stored properly they would have probably been excellent barrels. I ordered 3 of these, and on inspection 2 of the 3 had noticeable rusting at the muzzle ends of the rifling. This was detected on visual inspection of the muzzle ends with a bore light and confirmed using a bore scope.

These barrels arrived with vinyl caps covering both ends, probably sealing moist air inside. They were not packaged with silica gel or any other desiccant. The bores also appeared to be free of any corrosion protectants when they arrived. If Centurion had cut a hole in the breach end cap and dropped a silica gel pack into the plastic bag before sealing it, rust would probably not have formed.

I would not recommend this barrel to anyone who doesn't have the means to thoroughly inspect it for rust.
