what's stopping you? cost?

I think they're like $30k. Definitely not cheap. And even if they legalized full auto weapons, I have to image that there would still be the FFL application process. And those fees are really high, too. It wouldn't surprise me if it cost $50k when all was said and done. Maybe even more. I think I'd rather go to one of those places in Vegas where you can rent one to shoot at the range, and take the money I save and buy more Bitcoin. As cool as it is, I would feel bad knowing I spent all that money on a gun that just sits on the shelf most of the time. I got a Sig Sauer P556 SWAT for about $2000 that I like to shoot once or twice a month. And it's an incredible personal defense weapon. That satisfies my desire to shoot and protect my home.
