Hey Tony hook me up! 
I buy weapons because I enjoy weapons. I have my hunting and I have my self defense weapons and then I have my "why" - "because I can" weapons. I'd buy one of these in a second just to own it. If I can legally own it, I'm a law abiding citizen who's never even been arrested and love god and country but if it's legal and cool - I'll buy it. Heck I have no need for a Lamborghini in the US either but if I had the cash I'd own one just because I could.
