How so? Why else would they change something that has worked forever. Its not because someone felt like it. Its because someone demanded a cheaper process. Someone making the decisions wanted the cost of manufacturing a rifle to be less; thus the change in processing. Those decisions are made by people focused on the bottom line and nothing else. They now can pat themselves on the back and tout the fact that they took $X million out of the manufacturing process. What they are oblivious to, is the added costs of warranty returns coupled with declining sales because of poor quality. Next year it will be the same. They will look at the bottom line and see the year over year decline, and their first thought will be "MAKE IT CHEAPER". Never will they look at each other and say, "let's make a better, higher quality product so people will want to buy it". Like I said its a death spiral.
I know this because I have seen it, lived it multiple times (trust me, I'm old enough). The financial geniuses (accountants, not engineers, not manufacturing people, ACCOUNTANTS) that are running the company, ignore the advice from the people that actually know the processing and the product, all in a desperate attempt to make that bottom line look better.
