A free mod for 7 Days To Die, by LordHesbic.
Hesbic’s Better Robotic Turret Magazine Size is a mod that lets you change the size of the Robotic Turret Magazine. This means that you will be able to carry more ammo, and it is more likely that you will be able to kill enemies with the help of your allies.
This mod is based on an idea that the game developers had to implement in order to prevent players from accessing unlimited amounts of ammo. In order to do this, they decided to restrict the amount of ammo that you can carry.
You will need to download this mod in order to install it.
