FAD with Stalker is pretty good. If you can get used to the rate of fire then you can near enough get a headshot every time.

M4A1 is also just like the ACR. MP7 is just crazily accurate, get the first shot off with it and they're dead. P90 is always a favourite of mine also

Underrated? Id say M4A1. That rate of fire matches me perfectly. I don't mind prestiging because of that and the L118. I use those exclusively until pp90.

M4A1, its almost exactly the same as the ACR.  I used this with a silencer up until around level 55 and got every challenge for it except headshots and weapon level 31.  Its just an incredibly effective weapon.

Just started using the PM-9 yesterday and it is a really good gun.

Best two versions, IMO:

1. Extended mags with kick.

2. Rapid fire with kick.

Kick is a must.

I find the P90 to be quite good and people look past it when they see the PP90M1. I use rapid fire & Suppressor and it works a charm. Also I think people underestimate the M60. I love using that thing once I unlock it.
