M16 6.8 SPC Bolt Carrier Group features construction using both 8620 and 9310 steel.

The carrier itself is machined from hardened 8620 steel.

  • Quality assured with magnetic particle inspection
  • Rubber insert and spring included in extractor construction
  • Matte-black nitride finish provides reduced friction and increased rust-resistance
  • Properly torqued and staked gas-key screws

 M16 6.8 SPC Bolt Carrier Group also comes complete with a firing pin, cam pin and firing-pin retaining pin.
