The Shaw AR-15 Heavy Barrel in 6mm ARC with spiral fluting (brand part no. AR15HBSSHF186ARC) wraps helical flutes around an 18-inch stainless heavy profile, cutting weight and adding cooling surface with a distinctive twist-cut look. Shaw Barrels pairs the fluted tube with a rifle-length gas system that meters the 6mm ARC gently for smooth cycling and reduced felt recoil. Among rifle barrels, this spiral-fluted Shaw favors precision AR builders who want function and looks in the same 6mm ARC tube.
