Primaries level up from use, unlocking customization options in different slots. Slot availability varies by gun. It looks like all weapons have skins (great for the fashion game). The slots I've found so far include:
sights (different sights to taste, or trade off zoom <> ergonomics)
muzzle (recoil patterns mostly)
grip (recoil <> ergonomics/laser/flashlight)
magazine (capacity <> ergonomics/reload speed)
Looks fun! I kinda wish we could slot a bayonet but I can see why they would keep that exclusive
Changing course but have you had a chance with ergonomic values and others
Like for old illuminate loadout I used crossbow,
Bots double edge or charge up plasma, and bugs my beloved cookout. So not exactly precision guns mostly explosion or spray and pray
Edit never finished my thought but is a difference in 2 ergonomics noticeable
Just looking at the difference between angled grip and angled laser grip since I feel those guns don’t benifit much from recoil reduction
