The Faxon FF308BCNITRIDE bolt carrier delivers enhanced durability and reliability for AR-308 builds through advanced nitride coating and precision-machined 9310 steel construction. This bolt carrier group handles the increased pressures and stresses of .308 Winchester cartridges while maintaining consistent cycling performance across extended firing sessions.
What Makes This Different
Unlike standard phosphate-coated bolt carriers, the Faxon nitride-treated surface provides superior corrosion resistance and reduced friction coefficients. The 9310 steel construction offers 20% greater tensile strength compared to standard 8620 steel bolts, extending service life under high-pressure cartridge loads. This combination results in smoother operation and reduced maintenance requirements over thousands of rounds.Key Features
