I imagine its similar to buying a firearm. You need an FFL to receive it and they background you same as they would a gun. However the FFL needs a special license for grenades as well.

Edit for those who dont know:

You can order guns online but they must be shipped to a qualified FFL. They must keep records of having done a background check and all that (same as buying in person). As an FFL you could be audited at any moment so you dont wanna screw around or the ATF might come down on you hard. Honestly the last agency I want coming to arrest me is ATF looking at their history of shooting peoples dogs. Its like they think they are above all other agencies and do whatever to arrest people.

It's much more like buying a suppressor, SBR, or machine gun since you have to submit paperwork including fingerprints anddirectly to the ATF and pay the $200 tax. This whole processes take around a year.
