I recently purchased the 12.5 sauce pack bundle and everything is perfect. Fit and finish are great. The gas block is low pro and had plenty of clearance on my atlas S one handguard and everything worked flawlessly together while siting in my aero precision pistol build. I was getting good accuracy out of the barrel. I think it will get a little better as I get everything broke in a bit.

Great quality, barrel fit nicely into my aero upper. Highly reccommend. great pricing too

Absolutely love this on my newest build. It’s become one of my favorites immediately. Craftsmanship and packaging were both well thought out, and well done. I’m a believer and definitely staying a part of the #barrelgang for a long time now.

I purchased my 12.5 Sauce Pack through another retailer but I am extremely happy with it. About 500 rounds through it so far and I have gotten excellent accuracy with garbage tier .223. I’m running it with a VLTOR A5H2 and get perfect ejection with Brass. It’s a touch undergassed with steel but not enough to cause a malfunction yet.
With my suppressor it’s overgassed with brass ammo but completely manageable even when doing bill drills. Overall, for the price I don’t see myself buying anything besides Rosco for any of my future builds. Would absolutely recommend.

TL;DR I love it a lot and I will build the rest of my rifles with these sauce packs.
Super smooth and consistent performance right from the get go. Assembled with a Midwest combat handguard, a RTB upper receiver and an 80% lower. Uses a solgw nox muzzle device. Most reliable and smooth shooter I’ve ever had. If I shoot 100rounds in the same spot then I’ll have one neat pile of brass to pick. Supremely consistent recoil impulse and ejection pattern. Leaves light ejector swipes though. Enough to leave a bit of a burr. But not enough for concern. Even this is beautifully consistent.
And this setup has been 1moa accurate. My favorite blaster and I pine for my rifle when I dont have it in my hands. Excellent work Roscoe, I evangelize your products on the account of this exceptional performance.
I will absolutely buy again and the next will be a 14.5. I’d like to see a k9 gas profile on the 12.5 bloodline series.

I wanted to wait to write my review until I had a good amount of rounds put through the firearm and I absolutely love the 12.5 sauce pack! At first I was unsure with running the K9 gas system suppressed but pairing it with a Geissele super 42 H2 buffer I get perfect 3 o’clock ejections and a super accurate firearm. I would 100% recommend this to anyone looking for a 12.5 build
