14.5 inch nitride.
No make on it. Came off a high quality build so I'd assume it's a good barrel. I don't recognize it. Would like to know what it is before I advertise it for sale.
I will say that the finish on this Diamondback barrel is pretty nice. I think in the grand scheme of a build, the barrel isn't really that important. As long as it doesn't blow up, it's probably pretty good haha.
