Re: Barrel fluted to the muzzle???
Kind of makes the barrel look like it really was made from a truck axle. I like the look. As long as the brake threads fully engage the minor diameter of the valley of the splines or flutes that is, I don't see why a brake couldn't be installed. I'm sure Kirby could figure it out and make it work.
Build a man a fire and you heat him for a day.
Set him on fire and you heat him for life.
Only accurate rifles are interesting.
