The Faxon Firearms AR-15 Barrel (brand part number 15A58M14NPQ) is a 14.5-inch 5.56 NATO barrel cut to a lightweight pencil profile, keeping weight down to just 1.15 pounds for a fast-handling build. Finished in nitride with a 1:8 twist, it stabilizes the full range of common 5.56/.223 bullet weights and runs a mid-length gas system sized for a 0.625-inch gas block, timed for smooth, reliable cycling. The muzzle comes threaded to accept standard-pattern muzzle devices, and Faxon finishes the crown at 11 degrees to protect accuracy.
