Faxon Firearms DUTY 9MM 8.5'' 1-10 TWIST TAPERED CONTOUR BBL NITRIDE 15A910N8NLQ

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.
