Basically, "YES" is the answer.
Rancid Sumo--When you order from CMP, they send it directly to you at home. Be it ammo, be it a rifle, makes no difference. Somehow, coming from CMP, you are trusted to receive it and deal with it responsibly, wheras if sent to you from anywhere else, it has to go through through an FFL; you are not competent to receive it yourself.
Unless you are an FFL holder yourself.
May have to do with the fact that you have to submit all that documentation to the CMP when first ordering from them, but it still strikes me as rather skewed logic.
It's nice, at least, for CMP orders. Get yourself a Garand and/or a M1 Carbine--sent to your house--while the supply lasts--the number available is finite and dwindling.
