Using our fully automated robotically-driven production line, we drill, ream, rifle, contour and assemble our barrels from raw bar stock to the finished product. These barrels are properly stress relieved after rifling, air-gauge tested, and individually checked for headspace. 0ur quality control system ensures they are dimensionally correct and bores fall well within their individual tolerance ensuring superior accuracy.
