weapon mounted shotgun?

[Piedmont Plinker]

my crazy little mind is always dreaming up crazy gun ideas. So i got to thinking, why doesnt anyone make a weapon mounted full-auto shotgun? I think that you could get something like an AA 12 and put a 150 round mag on it, and then slap it on a HUMVEE?
has this eer been tried, or is it just a fancy of my oer-imaginative mind?

 

[Titan6]

Okay, you now how they say there aren't any dumb questions?

Seriously though absolutely no military potential unless we are at war with the duck force.

 

[Dave McCracken]

It's been done. Aberdeen Proving Ground had in the 60s a pair of full auto 12 gauges made there on a ring mount with a coaxially mounted 9 mm subgun firing only tracers. Ambush Buster.

The South Africans before the revolution developed a bunch of turret mounted shotgun mechanisms that would alll fire at once, destroying everything nearby. In convoys, they'd leave the fore and aft barrels empty. Same idea as above.

For military uses, some utility. Dunno about civilian use....

 

[Titan6]

I had no idea. How did they overcome the massive heat generated by full auto mag fed 12s?

I don't see any advantge over center rifle type MGs maybe that is why it is gone.

 

[Ohen Cepel]

The South African version was multi barreled and IIRC it was more like a multi directional Claymore mine going off. Was designed to defeat near ambushes in the brush.

For that use, it seems like a great idea. However, is pretty limited.

 

[rustymaggot]

useless past 100 yards unless its loaded with slugs. and at that point its inferior to a rifle round platform.


might be cool on a truck during the impending zombie apocalypse. i mean that in the nicest way. im a big fan of crazy stuff built for just because. i think my crazy, dream weapon would be a .22lr minigun.

You guys scoff, but I think that in urban warfare sort of situations I think an auto shotgun would be more useful than a machine gun shooting rifle rounds. When you have people up close and in your face the extra spread might certainly be worth it... chasing enemies around with the turrent would be more like shooting skeet or rabbits than picking targets off with a rifle, anyway.

 

[MWenzel]

That sounds pretty cool! but what would we use it against.

 

[SeekHer]

There was a belt fed, tripod mounted full auto shotgun made for use in guarding, primarily prisoners, just after WW2…

There was a “Gatling” style as well and again for the same purpose…Crowd control, riot control, very close in fighting…

Figure 12 pellets per shell, 350 RPM equals 4,200 .33 to .38 caliber roundballs in the air per minute…

Think of the devastation of the above but also consider that the shotgun is multi-use…bean bags, rubber slugs, flechettes, tear or pepper gas bombs, etc. against a rioting crowd of inmates/POWs…very effective I would imagine…

Why it/they never became mainstream, I can’t remember but it would be a viable gun to reconstruct or redesign as I can see multiple applications in today’s world and on one of the “Discovery Channel” weapons segments they had one that had a side mounted drum magazine and they demonstrated it firing pepper pellets into a guys chest…

You would put the idea out of your mind very quickly if you were the one expected to carry or fire a 150-round FA shotgun; I've handled both the SPAS-15 and the USAS (with both box and drum), and the one thing you notice immediately is how HEAVY they are. With 6 boxes of shells in it or attached to it, they get a whole lot heavier. Maybe OK for some sort of pintle mount, but definitely NOT what you want to have to drag around with you.

 

[HeedJSU]

Amen to that. My local gun shop has a SPAS-12 for sale, and picking it up is akin to picking up a cinder block or two. I'd hate to carry it with enough ammo to make it viable for a FA shotty. Now a turret mounted or vehicle mounted application, I can see the uses there. In close quarters (I.E., narrow alleys, narrow streets) I would think it would be very useful as a riot buster. Just my 2 cents.

In my high school rapid prototyping class I developed a non functioning chain driven, belt feed shotgun action. It fed dummys no problem. I got it a box some where among the other crap in my apartment.

 

[Correia]

I'm a bonafide shotgun fanatic, but I'm scoffing.

So it takes up as much space as an M2 or 240B, but is only effective at close range, and has a fraction of the penetration? (even in urban warefare, people hide behind stuff)?

And since it is vehicle mounted, you have no guarentee that your going to be in urban fighting. One radio call, and you're off to the boondocks. Or you're guarding a convoy across the countryside, where the shotgun would be less than worthless. Wait a second, I've got to unbolt this 200 pound shotgun and throw on that spare M2.

I think there's a pretty good reason that even though vehicle mounted shotguns have been prototyped, nobody has ever fielded one.

Has already been thought of and done. Check out this SUV sporting twin full auto 12 gauge AA12 shotguns controlled by computer from inside the vehicle.
Fires at 360 rounds per minute, or 6 per second each, for a combined total of 12 shots per second, or 720 rounds per minute. The computer can be set to 3 round burst, double tap, full auto or whatever you want.

Then of course there is the remote control helicopter with mounted AA12 that can be used from afar to seek and destroy. Fitted with Camera and better electronics to be controlled remotely through an encrypted signal. You can bet there is nothing easier than strafing a target with a shotgun.

They can be loaded with all your traditional shotgun rounds which are combat effective in some situations. However if you want to see really combat effective, anti material rounds good on other light vehicles and what make them highly valuable for combat and are like mini grenades, check out this:

They are being offered in High Explosive (HE), High
Explosive Fragmenting Antipersonnel (HE-FA), and High
Explosive Armor-Piercing (HE-AP).Here is the rounds individualy:



Here is a link to a PDF about the FRAG 12 ammo types: http://www.defensereview.com/1_31_2004/FRAG 12.pdf

And a link to a review of the round and the shotgun:

I think that the reason why is because there is no need for one.

For applications where MGs and controlled rifle fire aren't the best application, the military already uses the Mk19 automatic grenade launcher as a vehicle-mounted and man-portable weapon with HEDP (HE & AP) & flechette rounds.

Shotgun rounds (buck) aren't penetrative of battlefield bodyarmor and slugs don't make sense when rifle ammo is cheaper, lighter, more accurate and has longer range.

Which is the real reason shotguns are not use in combat much anymore even in close combat.They are highly effective, but only if the opponent is not wearing body armor. Everyone wears body armor now. Insurgents often do, nevermind any actual nation we were to face who would definately have body armor as standard issue. Anything that cannot penetrate body armor is obsolete on a modern battlefield.

I'm glad I'm not the ememy.

Why would you want an automatic shotgun when you can have either a light MG (whole lot more ammo), a heavy MG (lot more power, lot more ammo) or a Mk 19 (automatic grenade launcher)? If you just want to lay a whole mess of lead down range in a short period of time, they do make a vehicle mount for the minigun. 3k-6k rounds a minute is plenty of lead, again, with a whole heap more ammo on board, better range, better penetration, and more ammo available in the supply chain.
