After turning down the barrel, we jacket a 416R Stainless steel match barrel in a roll-wrapped carbon fiber sleeve and load it under tension. We 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 we use is specially designed to move at the same expansion rate as 416R stainless steel. We drill holes into the carbon fiber allowing air to move around the barrel and vent heat quicker without any delamination issues. Using the Carbon Fiber this way keeps the rifling straighter the warmer the barrel gets because it's under tension. This allows us to maintain superior stiffness and strength while keeping the barrel extremely lightweight.
