Eh, M40 was good in CoD4, Intervention is good in MW2. I really don't care as long as it 1 hit kills. I'd rather have the L96A1, AKA the world-famous AWM though, which is in BO, but too bad it's a peice of shit.
M40 awesome gun I just love it it feels much better when u kill someone with the m40a1 but when u kill someone with the intervention you'll become guilty.
