Q.C. is a double edged sword when it comes to manufacturing. From the bean counters perspective, it adds no value to the product and reduces the profit margin on every per-unit sale. But imagine how much more it costs the manufacturer when an action comes back to be corrected. And that doesn't take into account the damage done to the products reputation. That affects future purchases by not only that customer but other potential customers.
A slightly higher (relatively speaking) up front cost to accommodate a rigorous Q.C. program before an action went out the door would surely be preferable to the customer having to pay a craftsman additional money to correct it before it went into service. And when thinking of an action that has given problems in use and then comes back for corrective work....just imagine how much time and resources have been spent by that time.
Granted, we're talking about top level competition grade actions here. For a 700 clone, people just want an action they can take out of the box, wash it off and get a barrel fitted to it. There are some really good clones out there for their intended use. But the difference between even the best 700 clone replacement and a top shelf competition action is like comparing a lowered Honda with a fart can on it to an NHRA Pro Stocker.
Hope Florida is treating you well, Alex.
