Faxon Barrels Are 100% Manufactured in Faxon Firearms Factory From Start to Finish

In order to maintain their reputation as a leading producer of barrel on the market Faxon believes it is important to ensure that the entire manufacturing process is done in house at their factory from start to finish. This is why each barrel that comes off the production can be relied upon to perform its duty flawlessly. It would be a fools errand to attempt to locate a better barrel for your modern sporting rifle.

The Faxon AR-15 barrel is fully stress relieved along with being air gauge tested and magnetic particle inspected for quality. Additionally it is constructed from 4150 mil-spec barrel steel and utilizes a Government/SOCOM profile. The tale of the tape shows this barrel features a 16" length and is chambered to use the 5.56 NATO cartridge. An M4 barrel extension is used in order to allow for reliable feeding from magazines and a standard .750" diameter gas block diameter is used for maximum compatibility with after market gas blocks.
