I've never owned a DD, but have always wanted one just to round out the ol' collection. I fired an M-79 Grenade launcher in the Navy and wanted one ever since. Any of you guys got a 40MM of any kind? Last I heard a decent one was costing near $2,500.00. A bit more than I have ever been able to afford. That combined with some really expensive ammo.... Karl.

I have seen them for like 1800, and practice rounds are fairly cheap and not restricted though each HE round also carries a tax stamp so thats an additional 200 buck per HE round

I heard BATFE did away with the seperate tax stamp IF you had a registered 40MM. I don't know if that is true though. You only would have to pay the seperate $200.00 if you didn't have a registered weapon that shot them. That would be nice. But even just practice smokes are fun. Karl.

Nope each HE round is a DD on it's own, even flash bangs, every one used by the Police has to come in and out of NFA records.

You can shoot the behive rounds, chalk, and White Phos. but not HE.

Check out spikes tactical for 37mm. Theyre inexpensive to buy, the ammo is kinda pricey, and you can shoot a variety of rounds through them. Good thing is that they dont have to be registered with the ATF unless you want to shoot he or some of the other DD rounds.

S&W makes a 40mm but you better have $$$$$$$$$$$$$. ABN's 37mm is just as nice and just as fun and can fire DD and non-DD rounds just as well. Spike has adaptors where you can shoot flares but that's another legal issue.There are different smoke rounds I've found at www.fire​quest.com and www.ammu​nitiontogo.com

Penn Arms pump action 6 shot. But get ready to dish out the funds for the ammo.

Why get a M-79 when you can get a M-203 to fit under your AR. It's 37mm, does not require a tax stamp unless you plan of using rounds considered to be DDs. Every round that is not a flare, smoke, or 12 gauge 'wildlife control cartridge' is considered a DD. Furthermore, a 12 gauge adapter inserted into a 37mm launcher is considered to be a DD. I also don't think that the M-203 launcher with a 12 gauge adapter firing a 12 gauge round is a good idea because I don't think the launcher was designed to handle that much kickback. The wildlife control cartridges are made by blammo, along with other interesting rounds and by themselves are not considered DDs. Of course they were intended for use in a shotgun, not an adapter. I got this info over the phone directly from BATF while requesting paperwork for a homebuilt sound supressor. They were fery cordial and helpful. Basically if you have a clean rcord and pay the tax stamp you can do almost anything, incluting owning a tank with armorment, or a Cobra AH with armorment. Obviously these items are really big bucks. Also, what looks better hanging on the wall when guests come over, an M-79 or an AR with a M-203 with handguards, sights, and a bayonet? Certainly makes for great conversation, and is easily romoved to restore it to its original configuration and removed to a gunsafe and brought out for special occasions. Also, 37mm expended shells can be reloaded with smoke or flares and used without being a DD, or if you wish to break the law, reloaded with just about anything else including wooden dowels, bean bags, nails or anything that could hurt someone (not that a flare or smoke grenade couldn't). Cobray makes the 37mm launcher not only in the M-203 style, but other configurations as well. 37mm.com (recently sold to another party) has more info. John
