Faxon's Integral rifle barrels redefine versatility and precision for AR-15 enthusiasts seeking a compact yet adaptable firearm configuration. Designed with the modern shooter in mind, these barrels offer the maneuverability of a shorter overall length without compromising on the flexibility and compatibility that AR-15 builds are renowned for. With Faxon's innovative Integral Muzzle Device barrels, shooters are liberated from the constraints of a single rifle setup. No longer is there a need to rely on a gunsmith to pin and weld muzzle devices. Instead, users can effortlessly switch between a 3-port muzzle device or a slotted flash hider, enabling full assembly and disassembly of the barrel and barrel nuts. This freedom allows for endless customization and configuration changes, ensuring your weapon evolves with your needs. Crafted to be the pinnacle of value, Faxon Firearms barrels are manufactured in-house with meticulous attention to detail. Each barrel undergoes a rigorous process, starting with the selection of premium materials - either certified 4150 mil-spec steel or 416-R stainless. The barrels are fully stress relieved, air Gauge tested and feature an 11 degree target crown to guarantee superior accuracy. Quality is embedded in every step of the manufacturing process. From initial material selection to the final nitride finish, each barrel is subjected to a series of stringent tests. Precision custom hardened Gauges are used to individually check headspace, ensuring that every barrel meets the highest standards of performance and reliability. Choose Faxon's Integral rifle barrels for a shooting experience that combines precision, adaptability and unparalleled craftsmanship.
