===============================================================================================================================
What are the changes?
-updated to A20.6
-fixed all the iron sights best as i could.
-removed all the items that are not related to the weapons.
-removed all the ammo crate and box.
-all types of ammo are now craftable in the ammo workbench.
-the ammo workbench can be unlocked by its schematic or by perk advanced engineering level 2.
-5.56mm ammo (Normal, AP and HP) are the new standard ammunition for every weapon of the machine gun class, with a few exceptions.
-The crafting of 5.56mm is locked behind the Automatic Weapons perk book (volume 4 for the HP, volume 7 for the AP and completion for the bundles).
-5.56mm do less damage than 7.62mm but are more present in loot, easier to craft and cheaper to buy.
-added the Drum Magazine schematic and the M60 schematic because their respective books now unlock the new ammo type.
-added a way to re box all the ammo of the game to easier inventory management.
-45acp follow the same logic as 9mm, they are unlocked in the same way and affected by the same perks.
-all the weapons of the mod are not craftable, you can find them in loot or buy from traders.
-added new item cleaning kit used to repair all the weapons from the mod.
-slight balance to weapons' damage and fire rate.

===============================================================================================================================
The original mod is not mine I will not add new weapons or anything, I just edit the xml files for my personal taste.
I've made this changes for myself and decided to make them public because I think that also other people could like them, if you don't like the mod don't use it.
I'm available to fix eventual bug or errors and you are welcome to report them.
