I saw a video for this on youtube and it seems like the ultimate close range gun. Fully Automatic 12 gauge shotgun with no recoil....I'd never thought I'd see the day...
I had to look it up...the only AA-12 with which I was familiar was made by Vympel...with an active monopulse seeker and lattice fins for maneuverability...it was a formidable weapon...but a bit longer range than your AA-12...and a little heavy for carrying!
