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

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, so we will keep making quality and increase lead times. 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!

•  Lead Times are Currently 25 Weeks *

If you are shipping there is a tab at the top of the site page that will give you those instructions. If you have any questions give us a call! (480) 440-1878
