Rosco Manufacturing Purebred AR-15 223 Wylde 16" SPR Stainless Steel Barrel - Nickel Boron

The Rosco Manufacturing Purebred is a precision-machined 16" replacement barrel designed for AR-15 platforms and chambered in .223 Wylde, a hybrid chamber that allows safe, reliable cycling of both .223 Remington and 5.56 NATO ammunition. Part of Rosco's Purebred line, every barrel is machined from scratch in the company's Rhode Island facility starting from a blank of 416R stainless steel.

The SPR (Special Purpose Rifle) contour is well suited for cold-bore shots on target and was built to enhance the performance of Rosco's original SPR profile, making this barrel a strong foundation for precision carbine builds. A 1:8" twist rate stabilizes a wide range of bullet weights, from lighter varmint projectiles through heavier match-grade loads, giving the shooter flexibility across both .223 Rem and 5.56 NATO ammo selections.

Finished in Nickel Boron, the bore and exterior surface are treated for enhanced wear resistance, reduced friction, and easier cleaning compared to a bare stainless finish. This barrel is intended to be installed on a standard AR-15 upper receiver.
