Faxon 10.5" Gov't/Socom Profile AR15 Barrel, 5.56 Nato, Pinned Gas Block - 15A58C10NSQ-APGB

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.
