12.5 Inch Sauce Pack with Bloodline Nitride AR-15 Barrel

The Rosco “Sauce Pack” delivers high quality components for the core of your rifle build. This kit includes a 12.5 inch 4150 CMV nitride barrel with 5.56 NATO 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 9 and 11 inches, to keep the muzzle threads accessible but the gas block covered. If you’re planning to add a suppressor, check out the Sons of Liberty Gun Works NOX9 Flash Hider with Dead Air Keymount compatibility.

Check the fit

The upper was bent around the ejection port and the bolt wouldn't even go in. I had to pry the bottom of the upper apart which left small marks all over the inside. Once it was bent back out everything seems to to be working. I would definitely get a different upper that isn't so cheap!!!
