If you’re looking for a more robust mounting method for your gas block… look no further. Pinning your gas block, in addition to the use of set screws, gives the user the extra piece of mind that your gas block won’t shift or loosen while firing.
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.

So you want a lite weight upper...
Trying to build a lite weight upper so everybody knows Faxon pencil is the start. Start the build, every thing's good..until I'm ready to pin the gas block. No roll pin in the package, and the gas block wasn't tightened down as Faxon says they do. So, I find the roll pin info on Faxons site..5/64x5/16. Go to the hardware and buy it. Falls right through the hole. Find this Faxon has a 3/32 hole. Disappointed in wherever the screw up was, Faxon or AR15 sending me a return that was missing parts.
USLightweight and quality
Surprised how light it is. It will pair well with my JAG handguard in my WWSD 2021 lightweight patrol carbine.
