Elevate your shooting experience with our meticulously crafted pinned gas block barrels, designed to provide unparalleled stability and performance. By integrating both set screws and a pinning mechanism, we ensure that your gas block remains securely in place, eliminating any concerns of shifting or loosening during use. Our innovative approach simplifies the traditionally cumbersome process of pinning your gas block by pre-notching the gas block journal and precisely drilling corresponding holes in the included low-profile gas block. Each barrel comes complete with a pin and a gas block, which is hand-tightened to the barrel for secure shipping. Our Gunner profile barrels represent the perfect fusion of two legendary profiles - the robust Gov't and the lightweight Pencil. This unique blend offers the durability of the Gov't profile while maintaining the weight savings and maneuverability of the Pencil profile. The gunner profile is engineered to optimize balance, bringing the center of gravity closer to the shooter's body, thereby reducing fatigue and enhancing comfort for extended shooting, training or hunting sessions. Crafted with precision in Cincinnati, Ohio, Faxon Firearms barrels are the epitome of value and quality. Each barrel undergoes a rigorous manufacturing process, starting with premium materials - either certified 4150 mil-spec steel or 416-R stainless. Our barrels are fully stress-relieved, air Gauge tested and feature an 11 degree target crown to ensure exceptional accuracy. Throughout production, each barrel is subjected to a series of stringent tests, culminating in a nitride finish and a final inspection. We individually verify headspace with precision PTG Gauges, guaranteeing that every barrel meets our exacting standards for performance and reliability. Choose Faxon Firearms for a barrel that embodies excellence from start to finish.

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
