M203 40mm smooth bore?
Would a 40mm smooth bore on a M203 be a DD? Would firing 40mm chalk round through a smooth bore be DD?
Yes, a smoothbore 40mm is the same as a rifled one. Destructive Device.
The only 40mm rounds that are destructive devices on their own, are HE and HEDP rounds. Nothing else. GROG
After reading your "SAFETY" page. A 37mm chalk round would be a DD?
My airsoft launcher with a rubber projectile could be considered a DD?
There is no "ruling" on "chalk" rounds in 37mm. 40mm M781 "chalk" marking practice rounds are not considered "anti-personnel" by the US Military. They are not issued as part of the standard combat load of an M203 gunner for that reason. They serve no purpose in a combat environment, other than target practice. Remember, 37mm + anti-personnel round = the launcher is considered a destructive device. Gas, smoke, line launching, and flares are not considered "anti-personnel" in nature, and these are the specific types of rounds that are not intended to be fired at humans like wood and rubber baton, rubber buckshot, and bean bag.
For 37mm= Anti-personnel ammo + unregistered 37mm launcher = Launcher is an unlawful destructive device. Not the ammo. The only ammo that is a DD in itself is HE and HEDP explosive munitions.
I am not a lawyer. I cannot say what an ATF agent would think of a "chalk" round. All I can do is offer my professional opinion that, considering the 40mm M781 as written above, a 37mm chalk round would also not be considered "anti-personnel" as it is not intended for use against humans.
Now, that is not to say that, if you shot someone with one, you would be charged with unlawful possession of a destructive device and various assault charges, because use proves intent. Same as if you shot someone with a 37mm flare. You used it in an anti-personnel manner, regardless of the materials used in construction.
As far as the airsoft goes... As far as I know, airsoft is a toy, not a real launcher, so no, it would not be a destructive device. Now, if you modified it to make it fire real munitions, then, yes, it would qualify. Hope this helps. GROG
I read your other post. I have a ball with both my M203 and M79. I have both 37mm and 40mm barrels for my M79. It was completely built from scratch, with a lot of help from Destiny Densley with getting the receiver re-welded. It works very nice now, and was pretty cheap as far as M79s go.
This can be an expensive hobby if you stick with buying the real rounds off auction sites, but there is an alternative. I reload everything for my launchers. If you do any rifle, pistol, or shotgun reloading, reloading for the 40mm and 37mm will come easy. You will need some tools, and some metal working experience helps. If you are good with tools, you might consider it. Launchers are running pretty cheap right now, with the 399 ORF receivers and a 550 parts kit, you can have yourself something that will only increase in value, and be fun to shoot. I have a lot of fun reloading for it too. There is some additional information for the beginner here:
