The Faxon Firearms 8.6 Blackout 16-inch Black Salt Bath Nitride 416R Stainless Barrel (brand part number 110B863N16NMQ) gives AR10-platform shooters a factory-quality barrel for the heavy-hitting 8.6 Blackout cartridge. Faxon Firearms machines it from 416R stainless steel and cuts an unusually fast 1:3-inch twist rate to properly stabilize 8.6 Blackout’s long, heavy subsonic bullets. The 16-inch length keeps the build compact and maneuverable, and a Black Salt Bath Nitride finish locks in corrosion resistance and extends bore life. It is a purpose-built option for shooters running a dedicated 8.6 Blackout upper.
