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.
Build a custom AR22 conversion barrel. For use with AR15 to .22LR conversion kits only (.22LR to 223Rem Chamber Insert type). These barrels come with .217/.222 or .218/.222 bore and groove rifling but with a .223Rem chamber to accept various conversion kits out there but without sacrificing accuracy/velocity from using improper bore/groove diameter. No gas ports are drilled on these barrels. -----MUST BE USED WITH AN AR-15 to 22LR CONVERSION KIT AND FIRED ONLY WITH .22LR AMMO-----PLEASE READ BELOW IN OVERVIEW FOR MORE DETAILED INFORMATION.
Due to overwhelming call volume, we will not be performing order status checks on any orders still within their estimated lead-times. We will perform status checks on those at the end of or after the estimated lead-times. Email requests are faster as we're able to address them sooner than the phones.
Also due to overwhelming call volume, voice messages left with our Customer Support number may take quite some time to get a response. Our phone system sometimes overwrites voice messages left by customers so please either try again or send a message to firstname.lastname@example.org (as this email address can be checked and responded to anywhere by anyone here), you're far more likely to get a prompt response with an email inquiry than via phones for the time being.
Before placing an order, please double-check to ensure all details are correct beforehand! Delays involving order change requests continue to increase.
