The most important thing to be learned from those who demand "Equality For All" is that all are not equal...

Honestly, I don't see the reason for having such a short .308. I've got a 16" bbl 308. Honestly, it took a long time for me to even accept a .308 in this short of a barrel. If you're just looking for something fun that kicks more than your average ar-15, then by all means, go for it. I couldn't justify that much of a performance drop from a .308. As stated by others, if you drop the barrel length that much, it's closer to a 300 blk in performance, which is lighter, cheaper, and able to suppress much easier. I have a 5.56 AR in a 12.5 inch barrel and I love that.
I don't make the rules. I just think them up and write them down.
