Faxon 458 SOCOM Nitride Bolt Carrier Group

Perfect match for Faxon Barrels!

Faxon 458 SOCOM Nitride Bolt Carrier Group, FF458BCGCNITRIDE, is a Full-Auto rated BCG compatible with full-auto fire control groups and newer multi-stage trigger systems, fully MPI tested and manufactured using the finest U.S sourced raw materials available. The Black Nitride finish vastly increases the hardness of the steel, prevents corrosion, and highly resistant to wear. Other features include 45 degree chamfered bolt lugs, ensuring reliable action for high pressure hand loads and fast lightweight actions; meeting the standards for the most demanding operators. Furthermore, Faxon takes normal finishing to a new level with their “Super Finish” to further reduce friction and fouling, and increase smoothness of operation.

The Bolt Carrier Group is the heart of your rifle, and if you want to upgrade the functionality of your rifle, this is a great way to do it!
