Thanks to everyone for their input. I contacted the company & they did confirm that it was something that they had worked on for armed forces/law enforcement but they didn't know what the modifications were supposed to be for.
Dutch, thank you for the heads up. I'll have to look in to that. I did a little preliminary googling on what you were talking about but didn't get very far. I'll have to look into it further when I have a little more time. (Personally, I was rooting for the giraffe decapitator theory.)
Thanks again to all for the help.
