If it isn't an Atchisson Assault Shotgun it's a relative...

My first thought was it was a new video for the Knoxx mag adapters for Mossberg 500s & 590s, but that silly mag guide, apparently intended to slow reloads to the point where any survivors of your first "sweep" have a chance to bayonet you, threw that out.

Oh, yeah. HEY, DUMMY! USE THE SIGHTS! :banghead:

I WANT ONE!:eek::what:

What do you think he was shooting in that last mag.? That would be just the ticket for dove hunting

May 1, 2003, 12:12 PM
it could be one of the guns that S&W or HK builts as the CAWS, but those both required brass shells AFAIK

The latest in the Tactical Cat Removal Systems or TCRS's. They'er hell on Chipmunks too.:D :evil: :D

I've posted the link to the API List, and hopefully someone there will know what this is.

May 1, 2003, 02:23 PM
It is an Atchkinson, or something based on it. You can tell by the sights, and the guide for the magazines.

They are very rare.

Owen, the CAWS was a bullpup. The Smith was much different looking but in a regular configuration.

Skeet shooting would never be the same :D

May 1, 2003, 02:34 PM
Yep Atchisson. Very cool.

The sights and mags give it away.

May 1, 2003, 03:27 PM
On his second shot from the second mag (the last mag), at around 1:25 into the video, a huge flash lights up the reciever, was that an OOB? Its amazing that it continued to cycle with that occuring.

So much for the next "if fifty Zulus charged you at once which shotgun would you want" thread.

A select fire shotgun. Always impressive.

May 1, 2003, 07:39 PM
Ouch. My shoulder hurts.

I'd like to change my weapon choice for last weeks 'what if... zombie' thread, please.

And I'd call it the 'burninator'.

May 1, 2003, 07:53 PM
That goes on "THE LIST"

May 1, 2003, 07:54 PM
hmm.... other thread was looking for a good stray cat taker-outer....

I've never actually seen the S&W full auto shotgun, but I know a guy that did a lot of the design work.

Could you point me to a pic of it? (the S&W)

The AA12 Assault Shotgun is a weapon constructed with heat treated, corrosion resistant, aircraft quality stainless steel. It is gas operated, air cooled and fired from the open bolt. The AA12 is both box magazine and drum fed, having a rate of fire of 360 rounds per minute. When correctly fired, there is a counter-recoil mechanism incorporated in the design of the gun which reduces recoil to a minimum. This automatic shotgun may be fired single shot by releasing the trigger quickly after each round or fully automatic by holding the trigger to the rear without releasing it. There are no tools necessary for field maintenance and cleaning of this weapon. It best operates without the use of oils or lubricants and may be cleaned with soap and water. Removal of the barrel assembly only requires the use of a 3/16 inch allen wrench, while complete disassembly and assembly requires the use of fingers only. Within the design there is a cone shaped barrel extension which provides 100% positive feed.

General Characteristics
w/loaded 8 rd. mag: approx. 10.5 lbs.
w/loaded 20 rd. drum: approx. 11.25 lbs.
Loaded 8 rd. magazine: 1 lb.
Loaded 20 rd. drum: 3 lbs.
Barrel length: 19 inches
Gauge of Bore: 12
Chamber length: 2.75 inches
Operation: Full auto or single shot
with trigger control
Type of Action: Gas operated
Magazine: Detachable box or drum
Ammunition capacity: 8 rd box, 20 & 32 rd drum
Firing mechanism: Open bolt
Stock: Shoulder stock w/pistol grip. Right & left panels
serve as a protective cover
Rate of fire: Approx. 360 rds per minute

Note: The AA12 Assault Automatic Shotgun is specifically designed for Naval Military use only.
Therefore, some principles normally perceived of shotguns designed for sporting use do not apply to this weapon. [:rolleyes:] The AA12 is not a MACI (military adaptable commercial item).

Design Criteria
1. Total configuration and construction is based on factors perceived advantageous for a rugged military weapon used throughout the world- specifically in and around the ocean, seas, rivers, jungles, and deserts.
2. Firing from an open bolt to avoid cook-offs.
3. Large and small capacity magazine and drums.
4. Total construction, corrosion resistant stainless steel and high impact plastics.
5. Large durable components.
6. Simple design with minimum working components.
7. No tools required for field maintenance.
8. Open manufacturing tolerances to ensure functioning in any operational conditions.
9. Ability to fire consistently controlled single shots, short burst and full automatic mode. (Without a three position switch).
10. Minimum recoil directly to the rear.
11. Non-rising muzzle which retains target acquisition.
12. Protective cover for all funtioning assemblies which serves as a stock and grip for the weapon and protects the user from heat generated from firing.
13. Sights arranged to facilitate natural point instinctive firing without lowering the shooters head to the weapon.
14. Requires little or no oils or lubricants except in extremely cold, wet areas to prevent freezing. (CLP)
15. Requires little or no cleaning and can be cleaned with soap and water.
16. May be fired wet with magazine filled with water.
17. Can be fired easily by a small statured person.
18. Can be fired easily using one hand maintaining target engagement.
19. No special tools required for 2nd or 3rd echelon maintenance except for a 3/16 inch allen wrench used to remove a barrel binder screw, small hammer, and roll pin punches.
20. Virtually jam free due to design of chamber barrel extension.
21. Ability to see rounds in drum magzine.
22. Highly producible due to minimum number of components, having only seven machining operations performed on total components. Small number of weldments. Manufactured using easily obtainable materials. Simple design, easy assembly and disassembly. Total interchangable components, no final form fit and functioning of components. No final gunsmithing.
23. Safety switch and magazine release locations are compatible with other weapons in the system.
24. Easily stored and carried due to no protruding bolt handles or cocking handles on side of weapon.
25. Ability to withstand rough handling without firing when dropped on hard surfaces.
26. Color coding: the composite panel covers which serve as a stock and handgrip may be obtained in colors black, brown, navy gray, tan, and camouflage.
27. Ability to easily reload drums and magazines.
28. Ability to easily reload weapon in the dark while running.

OMG, that is FREAKIN awsome!!!!!!!!

I got to see one at a gun show back in high school around 1985ish.

It was full-auto and had a 20 rd drum. It has almost no recoil. It's 20ga I believe.

The one I saw was selling new for 200 bucks and the guy had a ton of 'em for sale. No one wanted one at all.

The only other one I've ever seen was in a class3 gun shop in Austin a few years ago around 1993. It had a $5k price tag on it.

Hey why not....gota have one in each collection. does it make sense....nope, but half the time i dont anyway

May 1, 2003, 11:23 PM
Personally, as soon as I get my SOT I am thinking a select fire Saiga 12ga would just be the ultimate LEO shotgun. With the adjustable gas system you could shoot everything from CS/OC rounds to slugs and have it rock in a big way.

I have an LEO/dealer version on the way and will see how feasable it would be.

The Wife was watching over my shoulder. Before I could even say anything, She said, "No, no way, no how." She's no fun.

a long-time friend of mine once told me a tale of how he and his partner had contacted Atchisson to license his selective-fire 12 gauge. After some negotiations, they never could come to a deal. At a later time, he came to learn that someone else had indeed been able to obtain a license to produce the design. Deposits were taken. letters of delivery dates were sent, and the money and the new licensees promptly disappeared.

Pity. Glad to see someone did make it, though. If this is an Atchisson design, I bet it's even cooler in real life.

And when you're done firing that many 12ga shells in that amount of time, your barrel can double as a cauterizing device....
