Dragunovs are on the list. They are not sniper rifles. They are squad battle rifles, meant to increase the firepower range of a squad, kind of like the army uses the M-14 EBR. EBR = Enhanced Battle Rifle.
That is the accepted name for this class of weapon. Everyone gets twitterpated by the Dragunov’s cool “Soviet Industrial” styling, and the scope (me too), but it’s a battle rifle.
The Barrett also is not a sniper rifle nut its anti material. The US Army even had no 50 BMG sniper round. Also the Mosin is a crappy standard rifle with some built better. Not sure why these rifles are in the list and no IW.
