Faxon AR15 9mm AR15 Barrel - 4.5" 4150 QPQ

The perfect barrel for dedicated 9mm AR15 pistol or SBR!

Works with Colt and/or Glock pattern 

Faxon Firearms barrels are the pinnacle of value. Manufactured 100% in-house from cradle-to-grave, these barrels are fully stress releived, 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.
