So, what about this gun will benefit the average swingin' dick GI?
More recoil
Heavier
Less ammo capacity/heavier ammo

Granted, it looks like a good replacement for the 249, but this is supposed to be the gun for everybody. Lots of analogizing to the M-14 going around social media...

Of course not much else since the M-16 has made sense. How much longer til dual equipped fighters get the M-17? Or is it going to remain an officer gun?
