Rosco Manufacturing Purebred 14.5" .223 Wylde 1:8 Mid-Length Sauce Pack Barrel Kit w/ BCG & Gas System - Sandblasted Stainless

The Rosco Manufacturing Purebred 14.5" Sauce Pack is a complete AR-15 barrel and gas system upgrade kit built around Rosco's Purebred line of stainless steel, match-grade barrels. The included barrel is a 14.5-inch chambered in .223 Wylde with a 1:8 twist and finished in a non-reflective sandblasted silver finish. The 1/2"x28 thread pattern accepts standard .223/5.56 muzzle devices, and the .223 Wylde chamber safely fires both 5.56 NATO and .223 Remington ammunition.

Sauce Packs are designed as turnkey drop-in kits that pair Rosco's most popular components into one matched bundle. This Purebred 14.5" kit is configured around a mid-length gas system and ships with the Purebred barrel, a Bloodline Bolt Carrier Group (rated for both 5.56 NATO and .300 Blackout), a matching Bloodline mid-length gas tube, and a Bloodline low-profile non-adjustable gas block. All components are manufactured in the USA to Rosco's specifications and are designed to install on a standard mil-spec AR-15 upper.

The 14.5" barrel length is a popular configuration for carbine-pattern builds. Note that on a rifle (non-pistol) build, the muzzle device must be pinned and welded to maintain a 16" overall barrel length per federal NFA regulations.
