Ah, I see now that currently non-compliant parts can in face be shipped! There are some limitations though, which I don't know if they're across the board and also illegal to ship or just individual company policies.
This is Palmetto State Armory as an example:
No Complete AR / AK Receivers
Non-compliant AR and AK rifles will not be shipped
So I guess buying an individual barrel, upper receiver, etc., is the way to do it?
I'm guessing is someone built a compliant upper it could be sent directly to a personal address.
EDIT: I just did some testing at PSA and it looks like they won't even ship a complete lower to an FFL, but they will ship a compete not fully compliant upper to a personal address. They will even ship an A2 flash hider, but that's a paper weight. Then it's off to pin and weld. (Does a thread protector also need to be pinned and welded?)
Nice!
I didn’t do tri tip, but I bought some hangar steak, and cooked it on the grill at the hotel. Rare, of course!
That, and one of my stuffed baked potatoes..beats going out for dinner.
