Is it legal to own an M79?


September 7, 2011, 10:37 PM
I just read about the M79.

Are they legal to own?

what are they classified as?

Living in NJ I am sure I could not have one even if legal in other states

Destructive device (DD) and they are legal to own. They do require registration and transfer tax on sale or purchase, and are very expensive. VERY expensive. Not sure about NJ state law.

NJ will not let you register a 10/22 if it has a flash suppressor and a bayonet lug (Legislature is very concerned about flash suppressed drive-by bayonetings)

Not much chance of registering an M79!

You have enough money you can own a Bofers 40mm anti-aircraft cannon! Perfectly legal in the right state, just prohibitively expensive for most of us.

But ya, the boarders are open! RUN!

Please don't tell the New Jersey Legislature that a Winchester Model 12 is a better weapon than a 10/22 with a bayonet lug.:cool:

M79. 40mm. Gun is a DD and most rounds are DDs too. All 40mm grenade rounds would be considered DDS individually taxed and registered too.

Actually, you can buy the practice rounds without DD paperwork. They have the orange powder in the nose under a blue plastic cap. But they are backed up by a solid slug of aluminum and, while not explosive, WILL penetrate a car door. :evil:

I think flares don't match the DD defintion either. (By grenades above I meant high explosives.)

Since military munitions are made in 40mm and no military munitions are supposed to be made in 37mm, there is a lot of civilian interest in 37mm relicas of M203. etc. and at least one webside featuring 37mm M79 stuff:

If an M79 has had the barrel removed, and had been declassified and reclassified with BATF, it can be registered a single barreled shotgun, but the barrel has to be at least 18" long. What this means is, you have a legal, regular M79 receiver, but putting a regular M79 barrel on it would make it illegal. You can also fabricate one with a smoothbore 37MM barrel, which would look just like a an M79, but could not fire 40mm ammo, and could be classified as a flare gun. The next best thing is buying a CZ RV85 flare gun. A very cool, all steel and wood single shot that fires 26.5mm flares and such. Not sure how NJ would look at that, but it is NOT classified as a firearm by BATF, and can be ordered through the mail.

Impact had one under the class3 stuff for sale. They are DD's and they are a lot of fun, even with the marker rounds. Since I can only have suppressors, AOW's, and DD's, I'll probably end up forking over for one one day. They are VERY accurate weapons.

I've shot the 203 and the 79. The 79 was more fun, the 203 sucks because it is heavy and not used all that much --but carried everywhere that M4 goes! I'd like one of those 6 or 8 shot revolver 40mm launchers they had on Future Weapons. THAT is cool.

Not sure what I'd use it for, but most NFA stuff has to be regarded as mostly a dangerous toy anyways.

You are correct and I misunderstood your earlier answer. I have a 37mm launcher mounted under the barrel of a Kel-Tec PLR-16 pistol and the 37mm market continues to grow.

A friend of mine has a 40mm grenade launcher for his SBR AR-15. He's got a stand-alone pistol grip for it as well.

M79, destructive device. $8200 at Impact Guns.

37mm is a form 1(gas cartridges),40mm is nfa,i think

Actually, 37mm flare guns are not even considered "firearms" under federal law. The 40mm is considered a "destructive device" largely because anti-personnel and explosive rounds are available. Since no lethal rounds are commercially produced for the 37mm, they are considered a non-problem. But if you take a 37mm round and somehow alter load it with lead be lethal, you are looking at a visit to Club Fed.

mortablunt: Guided anit-aircraft missiles are prohibited separately by

TITLE 18, PART I, CHAPTER 113B, 2332g

High explosive rounds are a non-starter. You need a licensed government approved storage facility. You also need a license to handle high explosives.

I've seen M203s for sale in the $1200 neighborhood (not including the stamp). That might be a cheaper way to get a true 40mm grenade launcher if M79s are in the $8k range.

Get yourself a 40mm grenade launcher and have your ammo transfered to your Class III dealer. Then bring the dealer out with you when you decide to drop a couple of those things. No transfer from dealer to dealer, and since your dealer is with you, no transfer to YOU for the rounds either. It always pays to have your dealer and his wife over for dinner once in a while. ;)

My brother came from our FFL's place day before yesterday and tells me Bill brought home two M79s that he bought for $800.00 (yeah, I said eight HUNDRED dollars) a piece.
They are exceptionally good friends, so 'older brother could get one for less than a thousand before the stamp.
Then he relates that "chaulk" rounds cost $18.00 ea..
He is willing to consider that simply too expensive to play with.

Wonder what a M203 w/ a smoothbore 18" bbl would do w/ the issue buckshot rounds? Not legal for duck, but would make a nice turkey gun.
