For years Engis has worked closely with manufacturers of firearms, as well as sporting and military rifles, to improve product consistency and lower costs. Engis Bore Finishing Systems have been successfully used in the precision honing of the barrel prior to rifling. Not only does our Single-Pass Bore Finishing technology improve the roundness and straightness of the barrel, it clearly enhances the cosmetics which are so important to the quality-conscious firearms enthusiast. In some cases, we have also improved the accuracy of bores in precision trigger assemblies. (less)
