H-S Precision’s Pro-Series and Pro-Series 10X cut-rifled barrels are recognized worldwide for quality and accuracy. Pro-Series barrels are produced only as match grade barrels, meaning end to end barrel uniformity of 0.0002” and exceptional internal finish. The cut rifling process, combined with the hardest 416R stainless steel used by any match grade barrel manufacturer, insures maximum accurate barrel life. Button rifled barrels require significant amount of hand lapping to insure uniformity. This lapping procedure rounds the corners of the lands and reduces barrel life. Cut rifled barrels require very little lapping because they are extremely uniform when the rifling process is complete. H-S Precision is the only barrel manufacturer that totally controls all of the manufacturing processes, including the design and manufacture of all tooling such as bore and chamber reamers, quality control gages and manufacturing fixtures. H-S Precision does not recommend any type of post-manufacturing barrel treatments, such as Cryogenics or other “miracle” treatment processes. We have a fully staffed Quality Assurance Department and maintain quality records on every barrel manufactured.
