I can't see a threaded joint in the picture, but when done correctly a profiled brake will have a near invisible connection. Like trying to find a taper pin that's been installed and ground flush...

If that is integral to the barrel I'd like to see info on what/how they did it. Drilling/milling holes in a rifle barrel creates burrs in the rifling- think semi AO gas port on steroids many times over. Why Magnaporting is done by EDM...
