Realistic Guns and Bullets Overhaul is a mod for the game Fallout 4. It brings more realism to the game and allows you to choose from a wide variety of weapons that were previously available in the game. It also lets you change the ammunition and the bullets. The goal is to make the weapons more realistic and to keep the game's structure intact.

The mod is based on the idea that every weapon has its own unique properties. The ammunition you use affects the damage and the velocity of the bullets. The length of the barrel affects the accuracy and the range. The heat and the chemical composition of the ammunition affects the fire rate.

All the weapons are realistic and they have unique properties.
