Bsf Barrels Rem Barrel Features The Bsf Barrels Rem Barrel starts with a 416R stainless steel match grade barrel a material prized for its machinability and consistent accuracy at the bench and in the field. Rather than wrapping the barrel directly in carbon fiber which traps heat and risks delamination over time Bsf jackets the turned down barrel in a roll wrapped carbon fiber sleeve loaded under tension. This tensioned construction keeps the internal rifling straighter as the barrel heats up during strings of fire preserving accuracy when a conventional barrel would begin to walk its point of impact. The carbon fiber itself is specially engineered to expand at the same rate as the 416R stainless steel which is the key to avoiding the separation problems that plague other carbon wrapped designs. With a 1:7 twist rate six grooves and a button rifled bore this .223 Rem barrel is built to stabilize a wide range of bullet weights for varmint hunting and precision shooting alike. The barrel carries a 5/8x24 thread pattern ready for a muzzle brake or suppressor and its .936 inch diameter strikes a balance between rigidity and reduced weight. Because the carbon fiber jacketing maintains superior stiffness while shedding bulk shooters get a stiffer lighter barrel than a comparable solid steel option without giving up heat management. The Bsf Barrels Rem Barrel suits competitive shooters and hunters who want to drop weight on a bolt action rifle without compromising the accuracy a quality stainless match barrel provides.
