Parts availability. In a SHTF scenario, you will always find other ARs. Same goes for AKs. Either is acceptable and anyone worried about such things would be wise to have at least one or more of each in their safe. I personally find ARs to be boring, but that doesn't mean I'm going to overlook one simply because everyone seems to have one. It's the fact that everyone seems to have one that I also have one in case I need it.Maybe...
But I just don't like ARs. I didn't like it then, I don't like it now. I feel that performance has always been a compromise. Length for performance.
But now, there is a real alternative. The Hellion is awesome. This rifle has everything I want and need.
Can you point out AR advantages compared to the Hellion? I am not asking this to be snide or confrontational, I really want to know your opinion and what factors you consider and why you put the AR in such high regard.
