Fyi, the response I received from CMP last week:
"Sir,
If your order was received by 10/3/16 it will eventually be filled.
Your order will go on backorder & we will fill the order when the armorers work up enough rifles to fill it.
We are currently working on orders from 9/12/16. You will receive an email when we get to your order.
Thank you for your patience & support of the CMP."
Looks like I may get my rifles.
