It is the responsibility of the manufacturer to ensure the quality of the parts received from the vendor. Full stop. No excuse for this one. Doesn't matter if it is firearms or anything else. Imagine Blue Origin CEO Dave Limp made a public statement to blame a subcontractor for the New Glenn explosion. Everyone would have called for his firing right the way. Whoever puts all the stuff together is the prime, it is responsible for the end product.
There is a difference between saying it is not uncommon to see failure in a part made by a few vendors vs it is not the responsibility of the company that uses the parts obtained from vendors. They are not contradictory. In fact, it points to a common problem, many manufacturers do not or do not know how to ensure parts they obtain from vendors. The fact this is not an occurrence unheard of points to that there are many manufacturers or assemblers getting the same parts from the few common vendors, and it is common practice not to have procedures, or the common procedures have a detection rate not high enough, to sufficiently detect the number of defective parts they purchased.
It could be price point, it could be simply they don't have or want to allocate the resources. It can even be they just do not know it is something they need to do. There is also a dilemma between the immediately traceable cost of good and the warranty cost that may come later. What it can get away with or simply the math doesn't go far enough to even anticipate warranty cost. Sometime warranty cost is a common bucket for everything and it can hide the true cost of a particular product amongst many if they choose not to track or care to look into it.
