X-Caliber Barrel & Mfg. offers the widest variety of contours and calibers in the industry. Our quality is equal to, or surpasses any of the big name barrel makers. All of our barrels are hand lapped and QC inspected before they are shipped to ensure the highest quality and greatest accuracy.

From QMA:

X-Caliber barrels have far exceeded our expectations in all rifle formats.  We have been extremely happy with the continued production of easy Sub-MOA barrels coming in from them.  At Quarter Minute Arms we have taken the guess work out of twist rates, contours, gas profiles, gas system lengths, etc. during your barrel buying experience, and we are providing you with the most successful options we have found during our personal development and testing processes for your next match-grade barrel.


  • 416R Stainless Steel
  • 1:8 Twist Rate
  • Gas System Length will vary dependent on barrel length
  • 1/2×28 Muzzle Thread
  • 11-Degree Crown
  • Polished SS Finish
  • Quarter Minute Arms logo engraved (No X-Caliber logo engraving)
  • Comes with a FREE Gas Tube


  • .750 gas profile will come in an SPR Contour
  • .875 gas profile will come in an AR15 Heavy Contour
  • .936 gas profile will come in an AR15 Bull Contour

We highly recommend purchasing a JP Enterprises bolt to be matched with your barrel prior to delivery.  Those can be found under “AR Parts” in our catalog.

***If the barrel does not say “in-stock” in the options above, then the ETA will be approximately 9-12 weeks from the date you order with us.  We will update you when the barrel has completed and is being shipped to us.  Thank you for your patience.
