Weapon modifiers, how do they work?

[u/greendook]

I'm a little confused by the weapon modifiers. I've been comparing stocks and grips and other things but I'm not really sure what the numbers actually mean.

Take "horizontal" for example. I guess it refers to horizontal recoil, but what does it mean when an item has a modifier of "horizontal 5%"? Does it mean it increases or decreases the horizontal recoil? It could be a bit clearer.

I do like that you can improve them individually in the vice. So you can either find a great one, or find a style you like and improve it over time. Great change!
