Faxon Firearms barrels represent the epitome of precision engineering and exceptional value. Crafted entirely in-house from inception to completion, these barrels undergo rigorous processes to ensure unparalleled performance and accuracy. Each barrel is meticulously stress relieved and air Gauge tested, culminating in an 11 degree target crown that enhances shooting precision. Our commitment to quality begins with the selection of premium materials, including certified 4150 mil-spec steel or 416-R stainless, setting the foundation for excellence. Throughout the manufacturing process, every barrel is subjected to a comprehensive series of tests at each stage of production. This meticulous attention to detail ensures that only the finest barrels reach the final stages, where they are finished with a durable nitride coating. Before leaving our facility, each barrel undergoes a final inspection, including a precise headspace check using custom hardened Gauges, guaranteeing optimal fit and function. With Faxon Firearms barrels, you are investing in a product where quality is not just a feature but a fundamental principle, ensuring superior performance and reliability for every shot. 11 degree precision target crown Twist rate - 1:14 Gas block diameter - 0.875 inches 1.1 gas block journal length Barrel extension for large bore Carbine length, button-rifled, gunner big bore barrel Magnetic particle inspection (MPI) for optimal performance to ensure optimal performance, it is essential to conduct magnetic particle inspection (MPI) with precision and adherence to established protocols This non-destructive testing method is employed to detect surface and near surface discontinuities in ferromagnetic materials By applying a magnetic field to the test object and introducing magnetic particles, any disruptions in the magnetic field caused by defects become visible, allowing for accurate identification and assessment Proper execution of MPI requires a thorough understanding of the equipment, materials and techniques involved, as well as strict compliance with safety standards and guidelines
