  We require that a bolt be headspaced to each 6mm ARC 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. If you are sending in your bolt please include a note in your box with your name, phone number and order #. Ship the bolt in a box, not any type of envelope, they can easily be damaged (happened on more than one occasion) Send it to MOS-Tek PO Box 50515 Mesa, AZ 85208. Thanks!
