Second, it's got a bull barrel. Haven't figured out why. Scout rifles are supposed to be light. This one's under seven pounds, barely, but it seems they could probably turn another half pound off the barrel.
Okay, that’s why it’s got a bull barrel. With 10- or 20rd box magazines, it can get really really hot surprisingly fast. My theory is that a thick barrel provides stiffness and thermal mass.
Still heavy, though.
