AA-12 

Argued as the most powerful shotgun in the world.

The Atchisson Assault Shotgun or AA-12

(AKA the Auto Assualt Shotgun) is the world's first

Full Automatic Shotgun.

It was developed by Maxwell Atchisson, and was developed priorly in 1972. It is capable of firing 300 rounds per minute.
(5 every second) Not only does the gun have a rapid fire rating, but is able to go as far as a normal assualt rifle.

It is capable of carrying 8 shells, with a drum barrel, 20 shells.
It can carry 3 types of ammunition: Buckshot, Frag-12 rounds, or Slugs.

Because of it's power, it is widely used in modern Military combat, and it now produced by the Military Police Systems Inc.

A Recent 2005 Model (Military Police Systems, or the MPS model for short,) has been issued and carries a slimer, lightweight look.

The gun weighs 5.2 Kgs with 8 shells, 7.3 with a drum barrel.

In other random events, the gun was featured on a 2007 episode of Future Weapons.

SWAT Member 1: So I recently heard you did a raid with the new AA-12 model.

SWAT Member 2: Oh hell yeah dude! They were packing heat, but before anyone of em' could fire at me, the whole damn room was covered in bullets.

SWAT Member 1: Holy shit...

SWAT Member 2: No Kidding... it was great though.

SWAT Member 1: I bet it was.

You see a camper, around the corner, holding a fully automatic shotgun, overpowered in every possible way, squatting there, waiting for its prey. This slutty bitch is hated by humanity. And now you're facing him in a head-to-head battle. You frown in despair.

Player A: Damn, that helpless motherfucker is spamming an aa-12 from 200 studs.

Player B: Pathetic.

AA 12 

The AA 12 is a shotgun that is fed through a drum magazine, and has 20 - 32 shells in it's drum. It is fully automatic, and the coolest shotgun ever, in my opinion. Best uses are:
1. Breaching and clearing a house filled with guns and drugs
2.Getting somebody off your lawn
3. Liberating some oil
4. Showing those hooligans that GOD BLESS AMERICA.

Sir! They won't let go of the hostages!

Hold my AA 12.
