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 JP Ent, Young Mfg, and RCA bolts head spaced to your barrel at our factory. You can buy one from us, or you can send us yours and we will head space it here for a $10 fee.
