Saiga Shotgun with GAT trigger device

So my buddy comes back from the big Crossroads of the West gunshow with an 8 round mag for his 12 gauge Saiga shotgun, and a GAT trigger thing. The GAT thing is a crank device that manipulates the trigger faster than you can pull it with your finger. It's legal. It makes the gun fire quicker, but it isn't full auto... again... it's perfectly legal. And completely useless. But man, is it fun! The Saiga is basically an AK-47 action converted over to fire shotgun shells. It's a good shotgun for some uses, mostly sporting. For hunting it's less than ideal, but not too bad. The combination of a GAT and a Saiga is just sick and wrong - and crazy fun.
