Reviews & Ratings for Rosco Manufacturing Saucepack Bloodline AR-15 .300 AAC Blackout Threaded Rifle Barrel — 3 reviews — Page 1

I got the 14.5 sauce pack to build my uncle a new upper and this is my first time buying the sauce pack. I was not disappointed. The label on the box is a hoot with nutritional facts. The upper came out great. Super easy to put together, super accurate and a joy to shoot. Everything comes well packaged too. All I needed was an upper and charging handle to complete the build. I highly recommend the sauce pack especially when it's on sale. Great value and excellent quality.

11.5 bloodline sauce pack. Top tier packaging. Showed up quickly. Gas block and gas tube aren’t as tight as I’d like em to be. Used a BCM gas block and tube. Barrel is beautiful. My third one. Pin gauges at .072 gas port. Feed ramps very nice. Perfect matchup to upper. Has snug fit to the standard upper receiver I used.(Not a thermal fit upper). The bolt carrier has a nice finish to it. Came nitrided. Specs and tolerances were good. I prefer phosphate and chrome. But supposedly theses bolts are headspaced to the specific barrel in the sauce pack. I did replace the extractor spring, o ring, and insert. With a Sprinco spring and O ring only. Ejector was a tad weak for me. Replaced it with a Sprinco ejector spring and new roll pin. I have NOT run it at time of posting. My Criterion 11.5 has a .069 gas port with a headspaced BCM bolt. So I presume this barrel will be just fine. All my Rosco barrels have been very accurate. I highly recommend Rosco barrels for the average man. Your next step up would be a Geissele, Criterion, BCM.

Everything looks great fit and finish. I can’t wait to put some down range.
