Hands down the best gig now is Capital Armory if you already have a print file and photo. I highly recommend using a trust in addition. Order online, submit documents and be home to sign for it when it ships.
I use a guy who works out of this house and is the actual NC distributor of all cans that come from them. He asked me what I don’t just use CA and save 6 hour round trip… I told him because I like to see the machine guns on the wall.
If you are new to the game you can use a someone with a kiosk and files single shot trust. Not my gig but the make it simple.
There are a few FFLs on here that can chime in and maybe simplify it. Message me if you need more info
