B-STOCK Faxon Duty Series 16in Pencil, 5.56 NATO, Mid-Length, 4150 QPQ Nitride AR-15 Barrel
Faxon B-Stock Products are items with cosmetic blemishes.
Each B-Stock product still undergoes and successfully completes our full battery of quality control testing.
These products still come with quality you’d expect from Faxon, but at a discounted cost due to cosmetic deficiency.
B-Stock Products are still backed by Faxon’s Guarantees.
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.
