Rosco Manufacturing Sauce Pack AR-15 Barrel - 13.7" - 5.56 NATO - Mid-Length - w/ BCG, Gas Block & Tube

13.7 Inch Sauce Pack with Purebred Stainless AR-15 Barrel

The Rosco “Sauce Pack” delivers high quality components for the core of your rifle build. This kit includes a 13.7 inch stainless steel barrel with .223 Wylde chamber, Rosco’s black nitride bolt carrier, along with the gas block and tube you’ll need for installation. All this make the “guts” of a high quality build – all you need to do is drop these parts into your upper and handguard of choice.

When choosing a handguard for this build, we recommend a length between 10 and 13 inches, to keep the muzzle threads accessible but the gas block covered. If you’re planning to pin and weld this barrel for a 16 inch overall length, check out the Sons of Liberty Gun Works NOX9 Flash Hider with Dead Air Keymount compatibility.
