    Not all Gas Blocks will work with all barrel configurations. If you order a barrel under 9" with a "Q" taper you WILL NOT be able to use a Rifle Speed gas system. If you order a barrel under 6" the Superlative Arms Block will not work. You will need to order a Side Control gas block. If you have questions about this please call and let us talk to you. We are always glad to work out details. (480) 440-1878

Gas System Length

  • Stainless Steel Gas Tubes

Gas Port Sizing

  • Not all barrel configurations are able to shoot both subs and supers. If we have a question or concern about your choices we will contact you to discuss options.


Barrel Finish

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

  • Standard Silver Bead Blast Finish

  • Cryogenics will add 2 weeks to your barrel lead time.

  • Carbon Fiber will on average lighten the weight of your barrel by 1/3. If you are interested but have questions give us a call! (480) 440-1878

Headspaced Bolt

  • MÔS-Tek Bolt

    We require that a bolt be headspaced to each 6mm ARC, 6.5 Grendel, 458 SOCOM, and 450 Bushmaster barrel we machine. 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 Type II 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! Questions? Call us! (480) 440-1878

Sig/Q Taper

  • 300 Blackout 1:5 Twist

    The Sig/Q Taper is a 25° taper added for specific muzzle devices and suppressors.
