Faxon Firearms 5.56 20″ Rifle-Length AR-15 Barrel with Gunner Profile in Black Nitride

The Faxon Firearms Gunner Profile – A combination of Government Profile and Pencil Profile.  From the extension to the gas block the Government profile was mimicked, but from there the Gunner moved to a .625″ gas block journal and the Pencil profile out front.  Secondly, by removing some weight from the front of the barrel, Faxon ensures versatility.  Lastly, heat resistance and whip are mitigated by keeping more of the weight toward the back of the barrel.

Faxon Firearms barrels are high quality and value.  Everything is 100% manufactured by Faxon Firearms.  Also, their barrels are fully stress relieved, air gauge tested, and 11-degree target crowned to ensure accuracy.
