BSF Barrels AR-15 223 Wylde 20" 1 in 8" Twist Carbon Fiber

BSF Barrels has a wealth of knowledge and experience in everything related to the manufacturing of carbon fiber products. BSF spent years developing this barrel to be the most cost efficient, accurate and versatile barrel on the market. Through various testing and opinions of fellow experts, the end result is truly an amazing outcome. BSF Barrels uses carbon fiber in a way that they feel is most effective. After turning down the barrel, they jacket a 416R Stainless steel match barrel in a roll-wrapped carbon fiber sleeve and load it under tension. This way, 95% of the carbon fiber does not touch the stainless steel creating air gaps and allowing air to foil around the steel and cool the barrel faster. BSF uses 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 they use is specially designed to move at the same expansion rate as 416R stainless steel. BSF machines openings into the carbon fiber allowing air to move around the barrel and vent heat quicker without any delamination issues. This also allows the barrel to stay mostly free from being in contact with the rifling itself. BSF has achieved a vibration dampening effect meaning the carbon absorbs the shock and vibration allowing a more consistent shot and groups. Using the carbon fiber this way keeps the rifling straighter the warmer the barrel gets because it's under tension. This allows the barrel to maintain superior stiffness and strength while keeping the barrel extremely lightweight. These barrels have been in development and testing for years.
