Manufactured in-house, 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 16" 9mm Carbine barrel

    Put barrel on new PSA 9mm hybrid carbine. Great reliability but poor accuracy with factory barrel. Went from larger than pie plate accuracy to less than 2" at 50 yards! Very happy with purchase!!!

    We haven't installed this barrel to date in a receiver, however the physical appearance and finish is fantastic. If it performs as good as it looks it will be awesome! The price is also friendly compared to other manufacturers barrels! Thanks Faxon
