A big weapon and attachments rebalance mod that I spent about a 6 mouths making and then another 6 mouths of just sitting on my pc so I desided to relese it and see what people like about it.
The main changes was to buff ammo pickup for dmrs and pistol, reintroduce the 180 and 120 ammo classes for assault rifles and smgs, nerf ammo pickup for the lmgs, buff sniper damage at the cost of ammo pickup and increase rate of fire for all single fire pistols.
Spread sheet with the new weapon stats can be found here.

Mod has support for LunaticLunarian's Allow Weapon Description
