This aptly named adapter known as the “beehive” or “hornet’s nest” allows you to load up to 10 .22LR cartridges, and (inserting one large pistol primer) fire them all through the little rifled steel barrels with one pull of the trigger on your 40mm grenade launcher. 40mm grenade launchers are considered destructive devices, and require a $200 tax stamp.
40mm chalk rounds and smoke rounds are readily available, but it’s the destructive ammo for them is hard to find, and VERY expensive. AutoWeapons.com is selling M576 40mm buckshot rounds for $125 each and on top of that each destructive round also requires a paid tax stamp. This beehive / hornet’s nest contraption seems like it would be great for practice, not to mention cheaper to run considering a box of 500 .22LR is around $20.
The major downside is that the adapter is $595 ( HERE on AutoWeapons.com ) but if your a 40mm fan, what you spend on this adapter you’ll make up for in ammo savings in a very short time.
I’d like to see one of these made for 37mm launchers, because they are not considered destructive devices!




Very cool
That must be a real blast to shoot (no pun intended).
“I’d like to see one of these made for 37mm launchers, because they are not considered destructive devices!”
If you had one, with an unregistered 37mm launcher, you would be committing a Federal Felony.
Any 37mm possessed with any anti-personnel round (which a 37mm version of this would be) makes your launcher a weapon capable of offensive or defensive combat. (A destructive device.)

hmmmmm good point Grog!
“…each destructive round also requires a paid tax stamp.”
To correct another mistake, no, each round does not require an individual tax stamp. The rounds for the 40mm grenade launcher do not require a tax stamp unless they contain more than .25oz of explosive material in the round itself, including any lift charge. This would only include HE, and HEDP type rounds, and not HE practice like the M407. The M407 actually contains two RDX pellets, and are completely legal to own, without any stamp or regulation.

I seen in shotgun newa a 37mm adapter for a single .22lr round. It staes it comes with an ATF letter. If it was a single or 10 round conversion wouldnt it fall under the same letter???

Its hard to stay inside the law on some of these items as the BATF doesnt know and make it up as they go along it seems??
fuck the atf they give weapons to mexico
trying to subvert the 2nd amendment obviously. approving of the atf is approving of treason
suck my dick jack sparrow, the mexicans are a well bred people!!
Oh they certainly are well bred – pretty good at it too.
Now if they would only care for their young instead of expecting handouts o stealing from others…
Hey Gene, yes, they do come up with some confusing things out of the puzzle palace sometimes… As far as a “Beehive” which I assume you are talking about, I have not seen a letter from ATF authorizing the single shot 22 conversion adapter at this time. I will check on it. The “Beehive” is a round of ammunition, and as such, would fall under the perview of ammunition for a DD or possibly AOW. Having a 12ga adapter in a 37mm, the launcher needs to be registered as either an AOW or a DD. I would assume this would be the case with the 22cal beehive also.

As you can see from reading the above sites, ATF seems to contridict themselves if there is a letter allowing a single 22 adapter. If you have a copy, please drop me a line at the e-mail grog@frontiernet.net. Thanks Gene, GROG
Hey Gene, There are a couple of sites on this, for your review:
http://www.atf.gov/press/releases/2006/05/050406-openletter-nfa-flare-inserts.html
and
http://www.atf.gov/firearms/guides/identification-of-nfa-firearms.html
If the 37mm is possessed with a 12ga adapter, it needs to be either an AOW or DD registered (the launcher, not the adapter). As far as 22 goes, I have not seen that letter, so I am not aware of any ruling or determination of the legality of a single shot 22. The above sites would seem to say that it would not be a “go” to have such an adapter with an unregistered 37mm. If you come across this letter, please drop me a line at the site, or at grog@frontiernet.net. Thanks Gene, GROG
Please erase the second one, I didn’t think it went through, thanks GROG
i was thinking it would be cool to shoot a belt of these out of a mk 19 but damn 600 a piece
These would not function in a Mk-19. The Mk-19 is a high velocity 40mm, the Beehive is low velocity 40mm. Two different animals, and not interchangable. GROG
what are you a fag or something Grog?
Depending on interpretation as to firing multiple rounds with a single trigger pull, a 37mm .22LR or whatnot beehive looks like it could easily be interpreted as NFA as a MG as well. Looks like suicide unless you’re doing it for personal amusement and have appropriate SOT status. I reckon 99 percent of BATFE and Judges would rule such an item a MG.
Is a derringer a “MG”?
in famous wordds of my relatives……..
kiss my assssssssss
I would buy 2 in 37mm.
Why all the hassle, 00 buckshot is cheaper, faster to reload, and does the same thing…?
I can buy 2, 12 gauge pump shotguns for 1 adapter.
108 .30 cal projectiles vs 20 .22 projectiles……
some people will buy anything.
The M576 40mm buckshot round does not require a stamp tax be paid for each round. They are considered the same as any other shotgun round. HE requires a $200 tax be paid as it is an explosive grenade.
