The gunner profile by Faxon combines the durability of the Gov't barrel profile with the lightweight agility of the Pencil profile. This design enhances maneuverability and reduces shooter fatigue by shifting the rifle's balance closer to the shooter, ensuring comfort and endurance during extended shooting sessions in various scenarios such as training, hunting or competition. Faxon's MATCH series barrels are crafted for superior performance and value. They are manufactured in-house from premium gun-barrel-quality bar stock, starting with 416-R stainless steel and featuring 5R rifling. This hybrid rifling design, with lands opposite grooves and minimized sharp angles, reduces jacket deformation, enhances velocity and simplifies cleaning. Chambered in .223 Wylde, the Match series barrels maximize the potential of 5R rifling, offering improved accuracy through reduced bullet jump. Each barrel undergoes comprehensive MPI testing to ensure safety and reliability. The barrels are nitride treated inside and out, enhancing bore longevity and providing robust protection against environmental elements. The barrel extension is coated with Nickel Teflon, offering exceptional dry lubricity and corrosion resistance. This coating ensures a precise fit between the extension and receiver, further enhancing accuracy. These features make the Match series barrels an exceptional choice for demanding applications, delivering unmatched performance and value when precision and reliability are crucial. 11 degree precision target crown Twist rate - 1:8 Gas block diameter - 0.625 inches Gas block journal length - 1.9 M4 - nickel teflon coated barrel extension Rifle length, 5R button-rifled gunner 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
