Okay, "frilly rifle" jokes and comments aside, it's been a few days since PSA posted on this (and we really do appreciate the explanation). But really, a bit more info is in order (at least that's the buzz from PSA Customers, both here and across the AR15.com board).
For the record, I've got two LPKs from PSA (recent) I'd like to know if they were PSA made or from this new supplier. I also have two PSA lowers built, complete with stock kits. So you could say I'm a bit of a fan.
The Country of origin question is a valid one which is the minimum that NEEDS to be answered, as some folks simply choose to buy Made In USA parts whenever possible, and that is their right. Disclosure of this fact is a requirement, not an option, if you wish to sell to those individuals. If it's not stated, the negative will be presumed and those parts overlooked.
As to the "mid quality", we either conjecture on our own, or we get specifics (frankly, a lot of companies are simply not going to get specific on their manufacturing processes, and I can't say as I blame them- top tier manufacturers of high quality generally will, as they generally show why their products are superior and therefore command higher prices).
I'd guess MIM parts at a minimum, but then again, even a number of parts in a high end LPK may be MIM for all I know (I don't). I do know when I spend $200 on a Geissele trigger, I hear about the manufacturing process (no MIM there). And I also know that MIM parts have come a long way, and are not necessarily sub quality or prone to breakage- though obviously parts machined from bar stock are superior, they are simply not needed in every case.
So, some detail on the different level of parts kits PSA is offering would certainly be nice. It would help those who buy from you to be informed consumers, and make intelligent purchase decisions for their needs, as opposed to simply guessing and buying ONLY based on price. Any info provided WILL be much appreciated!
