Italian Carcano, then probably China's hodgepodge of 19th Century rifles. I don't know enough of the MAS-36 to comment.As a child of the 70's, growing up during the Cold War, I have a distaste for anything Soviet.
I think the only reason so many people like Mosins is that they were so inexpensive (and that's a good reason! ).
Take any/all of the main infantry rifles of the WW2 combatants, price them all exactly the same ( pick a price: $200, $500, $1000, whatever). Which one would you choose to purchase last?
This, haha.
I bought a Mosin back when they were less than $100, then I bought a few more (another 91/30, an M44, an M38, etc)
Never really thought they were particularly fun to shoot, and they weren't impressive for accuracy out of a bolt action.
I got rid of all of them and the ammo when prices started to creep into the mid-upper 200's
Peasant rifles.
Jap stuff. Then Soviet crap.
I like Mosins because when I hold and shoot mine I think of the poor kid who got dragged into fighting the Germans and may or may not have a great comprehension of what was going on. Either way, his life was changed forever. Impressed into fighting in the World's largest conflict. I also think of the guy hammering away in a factory to produce it to try to save the Motherland from invasion. I really don't think the people fighting and crafting these were deeply invested in debating Das Kapital so whether or not they were citizens of the Soviet Union, it's irrelevant to me.
And for what it's worth, I routinely hear the Arisaka had the strongest action of all WW2 bolt actions.
