At the end of February I contacted Criterion about some accuracy issues I was having with one of their 6xc Remage barrels. Their rep who contacted me was extremely knowledgeable and helpful. He led the conversation with he wanted the barrel back and I would get a barrel that worked at no additional cost. I sent it in and it was determined that there was a defect in the barrel. An official order was placed and I figured it would be 6-12 months judging by the backlogs industry wide. I received a new barrel in 3 months. I was impressed with that. I installed the barrel yesterday and broke it in today. All groups have been 1/2” or less so far, shooting left over loads from the previous barrel. Very satisfied with my experience with a company that takes care of their customers.
