Original rusted then returned and got another rusted barrel - Christensen Arms AR-10 6.5 Creedmoor Carbon Fiber Wrapped Barrel

I bought one of these and all of the steel was rusted and even had fingerprints rusted into the steel, it came with no threar cover, and the threads were dinged. I returned it for another one. When the second one came in, it was rusted as well. Im very disappointed in the quality control of OP with these, especially for the price i paid. I got tired of waiting to build my ar10 so i sandblasted and cerakoted the steel parts of the barrel that arent covered by the carbon fiber. The overall construction of the barral seems very heavy duty. Waiting on ammo to shoot it now.
