Faxon Firearms has collaborated with Q to develop barrels specifically for their innovative new cartridge, the 8.6 Blackout. These barrels feature an impressive 1:3 twist rate, a configuration designed to harness rotational energy and maximize energy transfer to the target. Like all Faxon barrels, the 8.6 Blackout barrels are machined from raw bar stock at Faxon's manufacturing facility in greater Cincinnati. Each barrel undergoes rigorous quality control measures to ensure top-tier performance and reliability. They are fully stress-relieved to minimize internal stresses that could affect durability and accuracy over time. Additionally, the barrels are air gauge tested to verify dimensional accuracy and consistency. They also undergo magnetic particle inspection (MPI) to detect any potential flaws or defects that could compromise safety or performance. To further enhance accuracy, each barrel is crowned with an 11 degree target crown. Constructed from 4150 CrMV (chromium molybdenum vanadium) steel, known for its strength and durability, the barrels are finished with nitride coating. This coating not only provides excellent corrosion resistance but also enhances surface hardness and lubricity. Throughout the manufacturing process, each barrel is subjected to a series of tests and inspections at every stage to ensure it meets Faxon's stringent quality standards. This comprehensive approach ensures that Faxon 8.6 Blackout barrels deliver superior performance, reliability and accuracy, making them an ideal choice for shooters looking to maximize the potential of the 8.6 Blackout cartridge.
