16″ GUNNER, 5.56 NATO, Mid-Length, 4150 QPQ
*Though we stock barrels for builds, stripped barrels are usually drop shipped from the manufacturer in retail packaging. We cannot guarantee the accuracy of the “in stock” status. We can however accept back orders but please check Faxon’s website for availability.
Just what is the GUNNER profile?
The GUNNER (all caps, as it is that awesome) is the pinnacle of performance, weight, balance, and value. Designed by our competition shooting staff for those who value performance and versatility, the GUNNER profile is a blend of two of the best performing profiles of all time, Gov’t and Pencil.
Proving that every once and awhile, the Government can do something right, the GUNNER’s profile from the extension to the gas block mimics that delicious taper. From there, common sense takes over and the GUNNER moves to a .625″ gas block journal and our famed pencil profile out front.
Removing the weight from the front of the barrel ensures maximum versatility and keeps material to the rear to maximize heat resistance and mitigate whip.
The GUNNER is for real gunners.
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.
