Actually to replace just typing like "cl_righthand" but to make it easier and or not to memorize its command better use Workshop.


The first step is search "Crashz 'Viewmodel Generator" or Click Here.
After that click Subcribe button.


In the Main Menu section click Play > Find A Game > Workshop > Crashz 'View Model Generator > Start Local Server.




In the Workshop you only have to shoot in the settings you want and it's very easy.


To know all the commands you just need to shoot the Show Command section.


So that's how to change the right or left of CS:GO to make it easier for you to control Aim or some sort.
