  • Cryogenics will add 2 weeks to your barrel lead time

Headspaced Type II Bolt

  • Type II Bolt *

    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!

Sig/Q Taper

  • The Sig/Q Taper is a 25° taper added for specific muzzle devices and suppressors. You will know if you need this.

Available Services

  • You send us your components and we will send you back a complete upper receiver. Test fired and ready to go! We've got the tools! Put the guys to work!

  • Do you like a "Seamless Transition"? Send us your hand-guard and suppressor so we can make your barrel the exact length to hide the transition from barrel to suppressor. You don't need to use an FFL, we can accept your suppressor as "Gunsmithing". Easy!

  • We dimple our barrels! If you want a second dimple we can do that! Send us your gas block for correct placement, or purchase one from us!

  • We can pin your gas block to your barrel...in fact we will if that helps you out! We will drill it, then you can set the pin. We will need your gas block in order to set the dimples correctly. See shipping instructions for information on sending that to us.

  • We will install your muzzle device on your barrel then pin and weld it. It’s not going anywhere!

Current Lead Times (You must check the acknowledgment box)

We won't over promise and under deliver...We'd rather send your barrel to you early, then have it be past our estimated lead time. Machining a quality barrel takes time. We can't speed up the machines in order to lessen lead times, that will compromise quality and accuracy. We have recently brought in new machines and 2 more guys in an effort to shorten lead times. We are committed to making quality and that puts our lead times out. We apologize for the waits, and hope you will be willing to wait while we make you the best barrel we can. You are welcome to call with any questions! We are always glad to talk to you!
