Too Long; Didn't Read
Modern Firearms mod is a massive overhaul of Fallout 4’s combat. It replaces all of the vanilla game's original weapons and expands on it with an extensive arsenal of weapons from the real world. Modern sights made popular in Call of Duty and Battlefield are naturally included. Each weapon can be modified almost as extensively as in real life from the barrel length to the round it chambers, changing the way the weapon handles and letting you use the ammo that you want. Modern Firearms even adds weapons that aren’t commonly portrayed in the media.
