Either an Atchisson Assault 12, or it's current-production twin, the Mid-America Recreation AA12; they're open-bolt 12 gauges that can feed off a drum or a box.

Drum mags for Shotguns give me the heebie-jeebies. What happens if you get a hangfire? :eek:

With most shotguns, nothing that wouldn't happen exactly the same way with a tube or box mag; the shell doesn't fire, so nothing happens to move it out of the chamber. With a revolver-style shotgun like the Striker/Protector/Street sweeper, there's a slight (almost insignificant) chance that you'd be able to pull the trigger again before that hangfire actually fired, which would rotate that round out of alignment with the bore. A true hangfire is so rare nowadays that the possibility isn't even really worth worrying about; if it fires, it firea right away, and if it doesn't fire, it either WON'T ever fire, or it'll take another strike on the primer to get it to go.
 
yes indeed it has been posted before.... probably once a month:D :D :D

Specs on that gun....

The AA12 Assault Shotgun: is a weapon constructed with heat treated,

corrosion resistant, aircraft quality stainless steel. It is gas

operated, air cooled and fires from the open bolt. Th! e AA12 is both

box magazine and drum fed having a rate of fire 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 wren ch, 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.

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 the open bolt (prevents cook off).

3. Large and small capacity magazine and drums.

4. Total construction, corrosion resistance stainless steel and high

impact plastics.

5. Large durable components.

6. Simple design with minimum working components.

7. No too ls required for field maintenance.

8. Open manufacturing tolerances to ensure functioning in any

operational conditions.

9. Ability to fire co! nsistently controlled single shots, short burst

and full automatic mod e. (Without a 3rd position switch necessary).

10. Minimum recoil directly to the rear.

11. Non-rising muzzle which retains target acquisition.

12. Protective cover for all functioning 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

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 (Recommended clean and inspect every 2000 rounds).

17. Can be fired easily by small stature person.

18. Can be fired easily using one hand maintaining target engagement.

19. Tools, no special tool required for 2nd or 3rd echelon maintenance

except for one 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 magazine.

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 interchangeable

components, no final form fit and functioning of components. No final

Gunsmithing.

23. Safety switch and magazine release location are compatible with

other weapons in the system.

24. Easily stored and carried due to no protruding bolt handles or

cocking handles located 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 serves 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 with loaded magazines in the dark

while running. (Why would you have to run from anything when you have

this?
