Rosco Manufacturing Bloodline Sauce Pack AR-15 5.56 NATO 14.5" Mid-Length Barrel Bundle

The Rosco Manufacturing Bloodline Sauce Pack bundles the upper-receiver components builders need to put together an AR-15 around Rosco's 14.5" Bloodline barrel chambered in 5.56x45mm NATO (also compatible with .223 Remington). The barrel is cut from Chrome Moly Steel and finished in Black Nitride for wear and corrosion resistance, giving the typical Bloodline combination of accuracy and long service life under hard use.

Threaded 1/2x28 to accept a standard muzzle device or suppressor mount, the barrel is paired in this Sauce Pack with a matched mid-length gas tube and the gas block to drive it, plus a Rosco bolt carrier group rated for 5.56/.300 BLK. The result is a tuned set of upper components so you can move from unboxing to assembly without sourcing parts piecemeal - the gas system length is matched to the barrel profile and the BCG is set up for the cartridge the barrel is cut for.

The bundle covers the barreled-upper core: the 14.5" Bloodline barrel, BCG, gas block, and mid-length gas tube. It does not include an upper receiver, handguards, barrel nut, or any lower components - those are sold separately. Built around the AR-15 platform and intended for carbine, recce, and shorter-barrel duty builds that want the same 5.56 Bloodline barrel Rosco builds into its complete uppers.
