This Toolcraft 308 Bolt Carrier Group is finished in Nickel Boron and is designed for use in DPMS pattern AR10 rifles chambered in the 308 family of calibers. It is a full auto BCG and has forward assist serrations.

Nickel Boron is an extremely durable finish with self-lubricating properties so your AR10 cycles smoother and requires less lubrication. Toolcraft has the Nickel Boron finish applied by UCT Coatings of Palm City FL, the same company that applies it for Fail Zero BCGs. Called EXO Technology, this is a patented process that applies a Nickel Boron finish so durable that it is specified on Army 81mm and 60mm mortar tubes, Blackhawk helicopter hoists, and for hard use applications on some Navy ships!  IMO, this may be the ultimate upgrade to the All-American AR-10. And it looks good too!
