Sniper zoom setting

anyone know how to make the sniper aim in like how it is in halo 3 where you can hold to zoom in and toggle zoom also without going into menus and switching? I’m not sure if what I’m saying makes sense but if you get it please help I cant play without both lol

If your on pc you will have to check the hold to zoom function in the settings and bind your zoom change to a key or mouse button. I do not have it bound as 10x on the 2 maps currently is useless.
