Rosco Sp-Bl-105-556-Bcg-Gtc-Ngb-001 Saucepack+Urg
$337.50
The Rosco Bloodline Sauce Pack is a matched-component AR-15 build kit designed for shooters who want a proven ignition system without hunting down parts individually. This particular configuration bundles a Bloodline barrel chambered in 5.56 NATO with a complete bolt carrier group and gas system—all engineered by Rosco Manufacturing to function as a synchronized unit. Whether you're assembling a duty rifle, home defense carbine, or range gun, a quality barrel and BCG combo cuts through the guesswork and gets you shooting faster.
Rosco built the Sauce Pack concept after customer feedback: competitive shooters and builders wanted the core hard-use components pre-selected and priced as a bundle, rather than sourcing each piece separately. The Bloodline series is Rosco's in-house barrel and parts line, purpose-built for reliability and durability. By pairing their barrels with matched Bloodline accessories, you get components that are tested to work together, maximizing consistency and performance across the whole system.
This kit includes a Bloodline BCG (compatible with both 5.56 and .300 Blackout platforms), a non-adjustable Bloodline gas block, and a Bloodline gas tube sized for your desired configuration. The non-adjustable gas block is a straightforward choice for fixed-load builds; if you run standard 5.56 loads or a consistent ammunition diet, it delivers reliable lockup without the maintenance overhead of an adjustable design. Assembly is within reach of anyone comfortable with basic AR-15 work, and the matched components reduce the variables that cause feeding or cycling issues on first-time builds.
