All I know is that since Alexander Arms rebuilt one Grendel, and AR15 precision rebuilt a 6.5CSS and refaced the front of the receiver, I haven't had any issues with bolt failures. So far, thousands of rounds have gone through these rifles. Both companies have absoutely outstanding customer service. And I am quite critical of people who talk customer service, but don't deliver. Both AA, and Ar15precion are tops, and I wouln't hesitate to use either one.
