16" GUNNER, 300 BLK, Carbine-Length, 4150 QPQ
Just what is the Gunner profile?
The Gunner profile is a blend of two of the best performing profiles of all time, Gov't and Pencil.
Proving that every once and awhile, the Government can do something right, the Gunner's profile from the extension to the gas block mimics that well-known taper. From there, innovation takes over and the Gunner moves to a .750" gas block journal and our famed pencil profile out front.
Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear to maximize heat resistance and mitigate whip.
Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy.
Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges.
Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100 quality certifications.

Looks good, no defects or blemishes. Shipping was prompt. Barrel seems to be of high quality. I have not installed or tested it yet but still in the build process. It did fit well with my upper though during test assembly.
This is the first barrel I have purchased from Faxon. The barrel itself is very accurate. I was only able to get it sighted in but I would expect even better groups once broken in. I haven't tested the barrel for best group size yet but i had consistant 1" groups for sighting in purposes using a less than ideal rest. Even with that the barrel only took 8 rounds to sight in and punch center. The fit and finish were very good, although the gas port was canted to the right. I'm not sure if that is usual for Faxon barrels or not. Lastly, I had an issue initially. I ordered a .300 Blk barrel but I received a 7.62x39 Russian instead. I contacted customer service the same day and they sent the correct barrel right away. My only complaint is the second barrel was shipped with standard shipping. I would have liked expedited shipping on the second barrel due to the factory sending the incorrect barrel to begin with. At least Faxon paid for the return shipping . So far I'm pleased with the barrel itself, and only expect better results. I will consider another Faxon barrel in the future for another build
