Bioshock Infinite Volley Gun

The volley gun is insane. You can do a lot of crazy shit with this thing. It can AOE interrupt and damage foes, excels with most vigors to farm and disrupt foes, pairs well with virtually anything. IMO this is much better than the RPG due to ammo capacity and its ability to stunlock most difficult foes. Personally I like to run this with the shotgun, handcannon, or sniper rifle. Unlike the RPG, this weapon can damage firemen, as it deals physical damage.
