  • Product Description

    300 BLK with pistol gas system for optimum reliability with super or subsonic ammo. 

    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.

    1. Beautiful work

      So i got this barrel and have only put around 250 rounds through it, so far though I can tell you that the accuracy is on point for sure. For a 10.5 inch barrel it surprised me. If you are looking for a 300 blk out barrel and wanna go with this, dont even hesitate, just buy it. You wont regret it I promise. on 9th Feb 2017

    2. A+

      This is one of the more popular barrels we've been selling as many folks seem to be adding to their pistol/SBR collections. If you see the low price of these barrels and don't think they could be top notch, you're wrong! Give them a try. We don't sell anything we wouldn't use ourselves. The barrels from Faxon are among the best in the business. Get them before they realize their prices are to low!! on 6th Oct 2016

    3. Excellent Product!

      Great fit and finish. The barrel is lightweight and runs well on a suppressed SBR. However not necessary, minor lapping was required for proper match to my upper; but that is to be expected on any upper. I would recommend to anyone building a platform of this type. on 3rd Oct 2016

    4. Nice Looking barrel

      Fit perfectly and finish is sharp. I haven't shot it yet. on 15th Oct 2015
