  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 Gas Block will not work. You will need an adjustable block that has a side adjustment. If you have questions just ask, we are always glad to talk to you! (480) 440-1878

•  Perfect Fit * + $45.00

  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!

•  Double Dimple * + $45.00

  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!

•  Gas Block...Pin it! * + $45.00

  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.

•  Pin & Weld Muzzle Device * + $75.00

  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, 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!
