Hmm.Swiss rifles don't count.
Hmm.
Finn M28, M28/30, and M39, issue ammunition? Finnish Mosins had 1.5MOA requirements, so I'm sure a bunch of them were capable of 1MOA.
Assault Rifles didn't so much replace SMG's as they replaced Rifles, they also provided a weapon which was between a SMG and full length rifle.
Personally, I'd feel a little worried going into a fight with some of the lightweight stuff they put in these guns. I'd rather have more power and not need it than have too little power if the situation demands it. If I ever get stuck in the army, wonder if they'll let me bring a mosin along? Even a good deer rifle, maybe?
