Reviews & Ratings for Rosco Manufacturing K9 Sauce Pack Rifle Barrel — 2 reviews — Page 1

I run this 12.5” barrel suppressed all the time and it runs like a charm because of the patrol length gas system. It is softer shooting than a carbine length gas system but has enough dwell time to run consistently unlike a 12.5” mid-length. Additionally the ballistics are extremely similar to a 14.5” mid-length especially within 400 yards. I absolutely love the 12.5” patrol system, I have two of them.

I bought this because I liked the profile of the barrel and was interested in the new gas system length. After installing it, I zeroed it and found it to be just as accurate as my Triarc track 2.0 barrel with the cheap m193 that I was using. I was able to achieve about 2 MOA 5 shot groups with this, although this was just while using a red dot and shooting off of a bag on a hot day with cheap ammo. I’d expect it to easily be a 1moa gun or possibly better with 77gr or just some higher quality 55gr. After zeroing, I shot around 150 rounds through it while suppressed and found that it was smoother than my ballistic advantage carbine length 12.5 barrel and not quite as gassy. I do not use adjustable gas blocks, but it was not bad enough to bother me. A charging handle designed for decreasing gas to the face would solve that issue. I did run it with a bootleg adjustable bolt carrier group and found it cycled great on the 3rd setting (partially suppressed) with no noticeable gas to the face with a regular charging handle.
