.223 Revolver REDUX is a weapon mod for the game Fallout 4. It contains four materials, two types of receivers, and ammunition. 
The ammunition is capable of shooting both regular and power-upgraded bullets. 
The player can also improve the gun by adding different materials and fixing its caliber and the amount of ammunition. In order to improve the gun, the player needs to make a special tool that will help him to increase the amount of bullets that can be shot. This tool can be made by the player himself.
