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!
