Thank you for your comments.

The different uppers and barrels are exactly as described on our web page, no more, no less.

While we appreciate the efforts of OP to catalog our offerings, the opinions and speculations about origin he posted are exactly that - opinions and speculation, and are not any official PSA statement.   In reading through the content, though, it appears there is enough wrong information here that it will cause confusion for customers, and it would be easier for us to close the thread and delete it, rather than try to correct it all.  

This is a technical discussion forum for our customers, where we allow people to opine and communicate about our products.  We may, or may not join in on the conversation, but our choice to not join does not signify any approval of what is written, as long as the forum rules are followed, and folks keep it civil and family friendly.

Too much incorrect information to be helpful.
