Faxon Firearms
The Faxon Firearms 15A57C14N4P-Cl Duty 556 14.5 carbine barrel is a no-compromise replacement barrel built for shooters who demand accuracy and reliability in a compact package. Built on a 4150 Chrome Moly Vanadium steel foundation, this 14.5-inch barrel gives you the ballistic advantage of a full rifle round downrange while maintaining the handling characteristics that make carbines so popular for tactical work, home defense, and short-range precision shooting. The black chrome finish paired with mag phosphate treatment delivers corrosion resistance without sacrificing the clean aesthetic.
This is the kind of barrel that appeals to builders and gunsmiths who understand that a quality foundation matters. Whether you're assembling an AR-platform rifle from scratch or replacing a worn or damaged barrel, Faxon's reputation for precision manufacturing means you're getting a component that will hold zero and shoot consistently. The 556 chamber (5.56 NATO) is the standard for modern tactical and sport shooting, giving you access to a vast supply of ammunition and proven reliability across thousands of platforms.
At 14.5 inches, this barrel occupies that middle ground between the compact handling of a pistol-length system and the velocity you'd see from a longer 16-inch setup. It's a favorite among shooters who prioritize maneuverability in training or defensive scenarios without completely sacrificing downrange performance. Faxon barrels have earned respect in the builder community and among serious shooters precisely because they don't cut corners on material or manufacturing precision.
