Description

After turning down the barrel, BSF jackets a 416R Stainless steel match barrel in a roll-wrapped carbon fiber sleeve and load it under tension. They use this jacketing method rather than wrapping the barrel in carbon fiber because this method of wrapping has been proven to trap heat and cause delamination. The carbon fiber that BSF uses is specially designed to move at the same expansion rate as 416R stainless steel. Using the Carbon Fiber this way keeps the rifling straighter the warmer the barrel gets because it's under tension. This allows superior stiffness and strength while keeping the barrel extremely lightweight.
