Mark at Spartan Precision did two barrels for my AIAX in 6.5 mm CM. I don't normally coat my barrels because I feel they are expendable items. Mark did a great job. After I broke the barrel in I fired 10 rounds at 100 yards sitting on a bench. They were all within a 1/2" group. I am sure the rife will shoot around 3/8" group. I am extremely pleased and I recommend Mark for any gunsmithing requirements.
