I had a working one 2 weeks ago now its outdated,
but you can do this for fun,
1: Open console with this key ~
2: Type devmap mp_killhouse or what map you wanna play
3: while in game open console and type this in /cg_fovScale 1.3 or 1.5 or up (optional)
4: it will go passsed the default 1.3 is 110 im assuming
I have other working field of views for other call of duties if you like!
