Wow! I don't want one but when I was younger I would have. Mostly I am impressed that so much power can be run through an AR-10 platform.
It's kinda short for an AR-10. The 50 Krater is basically the same case, only quite a bit longer to fill the entire AR-10 magazine.

I am not an AR guy, but I have enjoyed the 500 S&W revolver.
I have always thought that a 500 Carbine or short rifle of some kind would be fun.
I know the 45 Raptor was shortened to address feeding issues. Does the 50 Krater run reliably while filling the whole mag?
