Faxon Firearms AR-15 5.56 NATO Pencil Barrel QPQ - 10.5

 Our pencil barrels are the lightest in the industry. Don't take just our word for it, major companies like Robar, 2A Armament, and others choose Faxon pencils for their ideal balance of weight and performance. Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, these barrels are fully stress relieved, air-gauge tested, and 11 degree target crowned to ensure superior accuracy. Quality is imbued into our barrels from the start. We start with the best materials, either certified 4150 Mil-Spec steel or 416-R Stainless. From there, each barrel goes through a battery of tests at each operation until finished in Nitride and final inspected. All barrels are individually checked for headspace by precision custom hardened gauges. Faxon manufactures all our barrels in Cincinnati, Ohio under our ISO:9001 and AS:9100  quality certifications. Barrel Material: 4150 Certified Gun Barrel Quality SteelBarrel Type: Button Rifled Barrel Caliber: 5.56Barrel Twist: 1:8Barrel Length: 10.5"Barrel Profile:  PencilBarrel Gas System: CarbineInside Finish: QPQ NitrideOutside Finish: QPQ NitrideMuzzle Thread: 1/2-28 TPI (Threads Per Inch) Gas Block Diameter: .625" Gas Port Diameter: .081"Gas Block Journal Length: 1.1"Barrel Extension: M4 Weight:  .9 lbsMagnetic Particle Inspected!11-degree Target Crown
