Polygon Count for a weapon in 2018 standards?

What’s the Polygon Count for a weapon in 2018 standards?

I know many people said it ranges from 5000 polygons to 10000 polygons, but I noticed that many modders that mod the fallout games recommend for a good quality weapon in game to be around 20k to 50k polygons…

Just a little confused on what is a ok amount for a good quality game thats 2018 standards here is a few examples of the quality below:

So my question is how much polygons are in a game like killing floor or counter strike go? and if a 32000 polygon weapon model is ok to have?
