  • Barrel Length *

    The options for length on the 400 Legend stops at 20". There isn't enough data to suggest that going any longer improves velocity/accuracy. If you would like to talk to us about this please feel free to contact us! (480) 440-1878.

  • If you need a custom length let us know! When ordering choose the barrel that is closest to the length you are looking for, then leave a comment and we will be in touch.

Crown/Muzzle

400 Legend is a high pressure round. Due to safety concerns we do not offer this round in a 5/8x24 muzzle. If you have questions or want to speak to a gunsmith about this feel free to call (480) 440-1878

Barrel Finish

Adding Nitride/Cerakote to your barrel will extend your lead time out depending on our vendor lead times (Generally 2-3 weeks).

  • Barrel Finish Options *

  • Cryogenics will add 2 weeks to your production time.

Add a Head-spaced Bolt/BCG

  • Add a 400 Legend Head-Spaced/Tuned Bolt *

    This bolt will be polished, head-spaced and test-fired with your barrel. This is a critical part of cycling with the 350/400 Legend. We strongly recommend you purchase a bolt, or if you would like to send yours in, we will polish it for you. Please make sure your bolt is clearly marked with your name and order number.

Available Services

These are a few common services we offer. We offer full gunsmithing options too. Check out our Gunsmithing Section!

  • 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 will 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! $40

  • 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!

Shipping Instructions

Check "Shipping Instructions". This link will take you to the Mos-tek "Shipping Instructions" page. There are shipping instructions at the top of this page. Please follow these when shipping in your firearm. If you need clarification feel free to call anytime (480) 440-1878

    Current Lead Times (you must click acknowledgement 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!
