Match Grade criteria, the groove diameter must air gauge within .0003" of our standard diameter. Moreover, the uniformity of the bore cannot vary more than .0001" for the entire length of the barrel. These barrels are also completely stress relieved, and the bore is polished to a gleaming surface finish by our most experienced lappers. Match Grade stainless steel barrels includes hand lapping to a beautifully smooth surface. Chrome-moly can be lapped to a similar finish at an additional charge.
Every barrel is stress-relieved in a vacuum furnace, hand lapped, and inspected with a video bore scope. Quality is also assured through the use of our Sheffield Air Gauge System and Rockwell Hardness Tester. Stainless steel barrels are guaranteed to be dimensionally uniform to .0001″ and free from internal tool marks. Chrome-moly barrels are uniform to within .0002″ end to end. We do not have different grades of barrels in the two types of steel: just one, our best match quality.  Each match grade barrel includes the paired bolt- further insuring the ultimate match performance.

Our barrels are made in the USA from solid bar stock, head spaced and are ready to assemble. Gas port tuned for reliability with 5.56 or .223.
