I know the mod is no longer updated/Maintained
For player having this error:
Unknown equipment name: personal-turret-firearm-magazine-equipment-reload-36.400009155273 (or any other number at the end)
This is caused by ammo_stack having a floating precisiong value, to fix this:

In the folder AutoGun/control.lua
Line 50 and line 57; replace "ammo_stack.ammo" by "math.floor(ammo_stack.ammo)"
This fixed the crash for me

Thanks for finding, this looks like a float error, unwanted change by different mod or by change API that allow floating point ammo value.
