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.

***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.
