Ratings & Reviews
Gas port is too small for the dwell time of the system.
I purchased one of these only in blue rather than stainless. As provided I was unable to get the weapon to cycle. with the carbine length gas system. It required drilling out the gas port to enlarge it to provide enough back pressure to cycle the system. Otherwise, it was and is an excellent barrel. If it were not for the gas system issues, I could give it five stars with no question.
Good for the price

So overall the barrel seems great shooting 1 inch groups at 100 yards, however I have to manually charge every round. If running the jp scs you will have cycling issues, because cycling is non existant. Just my experience but customer service is top notch the are exchanging the barrel for the pistol length system variant. That's why it's getting 4 stars.
I love this barrel!

I've built two ARs with this barrel. Workmanship is good, overall quality is good. I love the carbine length gas system (very easy to tune) and none of the pistol-length crap. Accuracy is good for what it is (short). Very satisfied.
Get a pistol length gas system!!

Not enough gas pressure to push bolt back far enough to load another round. Garbage. Get a pistole length gas system.

high quality manufacturing. accepts gas block easily, lines up perfect. chambers and ejects rounds cleanly. shipped fast with no hassles.haven't fired yet but expect accuracy to be acceptable from the 10.5 inch barrel. Rifling and interior barrel appears unblemished. barrel mics even along the length. i can't find any faults.
