About the Faxon 16-inch Pencil Profile AR15 Barrel available at R&B Arms:
We took some of our most popular barrel models and took the biggest headache out of pinning your gas block by pre-notching the gas block journal and drilling corresponding holes in the included low-profile gas block.
Each Pinned Gas Block Barrel comes with the pin, as well as a gas block. Gas blocks are hand-tightened to the barrel for shipping.
Faxon Firearms barrels are the pinnacle of value. 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.
