Okay, right after thinking of this, i realized the stupidity as I thought of it as a console user, but what the hell.

Somebody needs to make a mod with two zoom buttons. Preferably the PC equivelent to the left bumber and right bumber.

Already been done and it works really well:

Instead of two buttons, you use the mouse wheel while scoped in.

Has Binocular zoom in it and can tech them out a bit.
The binocular overhaul part of it has been out for ages Works great also

Yes, but I plan to use an xbox controller to play it on the PC. As soon as I get it... v_v

Ahh. Well i didnt see that in your original post.

Should be able to use that then on your xbox controller. Assign buttons on your controller for mouse scroll wheel probably.
