    Barrel Finish

    Adding Nitride or Cerakote to your barrel will extend your lead time out 2-4 weeks depending on our vendor lead time.

    Type II Bolt

    • MÔS-Tek Bolt

      We require that a bolt be headspaced to each barrel we send out. The industry standard for Type II Bolts is too varied, and in order to ensure that you have a fully functional barrel your bolt must be headspaced correctly. You can either send in your bolt to be headspaced or you can purchase a MOS-Tek bolt. This price is for the "BOLT" only, not a complete "BCG".
