BSF Barrels SF3IYT0111 AR-15 .223 Wylde 16" 1:8 Carbon Fiber Semi-Auto Barrel

The BSF Barrels SF3IYT0111 is an AR-15 semi-auto barrel chambered in .223 Wylde, built around a carbon fiber-wrapped 416R stainless steel core for match-grade accuracy and reduced weight.

At its heart sits a precision-turned 416R stainless steel match blank encased in a roll-wrapped carbon fiber sleeve loaded under tension. The carbon fiber jacket keeps the stainless core cool during extended strings of fire and adds rigidity without the weight of a heavy contour steel blank, giving you a 16-inch barrel that holds accuracy, sheds heat, and stays lighter than an all-steel equivalent.

Chambered in .223 Wylde, this barrel safely fires both 5.56 NATO and .223 Remington ammunition, making it a flexible choice for an AR-15 build or upgrade. The 1:8 twist rate stabilizes a wide range of bullet weights, from lighter varmint projectiles up through heavier 77-grain open-pattern match and hunting bullets.

Manufactured in the USA, BSF Barrels combines modern materials with tight quality control. The barrel is designed for installation on an AR-15 upper receiver and built to feed reliably in semi-automatic fire.
