Most Helpful Positive Review Listed PW9. It Will work on any general style AR9 build. I used to get shipments of R&D.
The built PW9 are the same (Non-Ramped) ar9 barrels. the pw9 as a complete upper or a complete PW9 is a barrel with its muzzle device permanently attached to it. Those are fine as is on those guns. These PW9 barrels can go on any general style non ramped ar9 pcc or pdw diy builds if you wish. I ...

PW9 AR Pustol Barrel

by Kyle P, Verified Owner from VA, United States Written on August 25, 2024
Picture did not match item received not sure if they changed manufacturing process or design. While the barrel seems to be decent, it lacks the dimple to keep it from spinning once you install. Without the pin, I am unable to attach sound suppression devices as it turns continuously while trying to install.

Too good to be true.

by JeremyM4, Verified Owner from AZ, United States Written on May 2, 2024
I figured this barrel wouldn't be of very good quality, but for 80 bucks, it was worth the risk. The only problem i had with it besides it being shorter than advertised, is that the threads for the muzzle device are junk. Absolutely none of my flash suppressors or muzzle brakes will even start to thread on. The threads are so small, too small, that they bind up immediately. If you don't mind not being able to put a muzzle device on it, then this barrel is fine.

Faulty Machining Process

by Steve, from ND, United States Written on January 24, 2024
Got the 8.5 barrel that was to paired with a silencerco mount. Price and shipping time was fine, but when I received it, the threading of the barrel was off by approx. 3/1000 according to the gunsmith as the mount would seize when I tried screwing it on. A lathe, and precise filing was needed to get threading to a true 1/2x28. Keep this in mind when purchasing.
