Faxon Firearms Mid-Length Button Rifled Pencil Barrel 5.56x45mm 16", Black

For shooters seeking the perfect blend of compactness and flexibility, Faxon's Integral rifle barrels offer the ideal solution. These barrels combine the maneuverability of a shorter overall length with the compatibility of the AR-15 build. Thanks to the integral muzzle device, you no longer need to depend on a gunsmith for pinning and welding a muzzle device to the barrel. With the option to choose between a 3-port muzzle device or a slotted flash hider, the barrel and barrel nut can be fully-assembled and disassembled, allowing shooters the freedom to change configurations on the fly. Manufactured in-house, Faxon Firearms barrels are designed for superior accuracy and durability. Each barrel is stress-relieved, air Gauge tested and finished with an 11 degree target crown. Starting with premium materials like certified 4150 mil-spec steel or 416-R stainless, every barrel undergoes a series of stringent tests during production before being finished in nitride for enhanced longevity. Precision custom hardened Gauges are used to individually check headspace, ensuring the highest standards of performance and reliability.11 degree target crownIntegral slim flash hiderTwist rate - 1:8Gas block diameter - 0.625 inches1.1 gas block journal lengthM4 barrel extensionsMid-length, button-rifled, pencil barrelMagnetic 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 protocolsThis non-destructive testing method is employed to detect surface and near surface discontinuities in ferromagnetic materialsBy 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 assessmentProper execution of MPI requires a thorough understanding of the equipment, materials and techniques involved, as well as strict compliance with safety standards and guidelines
