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.
Note - Our 1 MOA Accuracy Guarantee is ONLY valid with RCA bolts head spaced to your barrel at our factory. You can buy one from us here.
Due to a logistical limitations and complications which arise with customer-supplied bolts (e.g. arriving too late, not properly documented, etc.), X-Caliber will now only guarantee 1 MOA or less on AR barrels with Rubber City Armory bolts that are purchased through X-Caliber.net and properly noted to be headspaced to the AR barrel on order (either via previous order # or through the same checkout cart as the barrel). Any RCA bolt ordered for an X-Cailber barrel in production, that is less than three weeks into production, will be headspaced to that barrel for no additional fee.
