Rosco Manufacturing Purebred Barrel, .223 Wylde, 16-Inch Nickel Boron Stainless

The Rosco Manufacturing Purebred Barrel is a 16-inch, .223 Wylde-chambered AR-pattern barrel constructed from nickel boron-coated stainless steel from Rosco Manufacturing (brand part no. PB-16-SPR-223W-7-M). Rifled with a 1:8 twist, it runs both .223 Remington and 5.56 NATO ammunition safely, and the nickel boron coating adds corrosion resistance along with a smoother bolt-carrier cycling surface. At 16 inches, it sits right at the federal minimum length for a rifle barrel, giving builders a full-length option for a precision or duty-style AR-15 upper.
