I know for a FACT that individuals have LEGALLY owned M203's and M79's (in 40mm) in Missouri.

I've never been able to reconcile how they are doing it.

Awhile back it appeared that BATFE was trying to reclassify 40mm Practice Rounds (Chalk Rounds) as DD rounds.

Thankfully it didn't happen.

Here is an IM I received from a post I made in the DD Forum, the respondent didn't want to post in the Forum so I'm not including his name...

Just replying via IM, since I don't want to deal with everyone telling me how I'm in the wrong etc. I registered a spikes Havoc in 40mm 2 years ago on a trust via Form 1 in Missouri. The legal question is up in the air, I called 3 ATF field offices in MO (I think it was that many), and got, 'Its legal, definitely illegal, I dunno but they won't approve it if illegal' answers. If you were going to do an M203, I would recommend buying the receiver on its own, doing the Form 1 on a trust, then buy the barrel.
