It says Bear Creek barrels. That's what Nikatkimber is using on his lightweight build.
Not the same barrel I'm sure but they build some decent stuff according to reviews
Mine functions fine, is dimpled for gas block set screws, and fit and finish appeared good. I have not however checked accuracy yet.
But for this kind of build, who cares on accuracy. If it functions, then mil-spec is only like 3moa if I remember correctly.
