In case you have no clue what NC weapons are nice to play with, here is my guide/opinion:
General attachment stuff: Dont use silencers, they know you're there.
Anything that is designed for long range: Compensator + foregrip if possible. HVA is nice as well.
CQC: Laser sight + IRNV scope.
EDIT: Implants.. use Clear Vision if you got access to implants. There will be plenty of concussions. And throw in an EMP before you breach a room. Often in those matches there are AI mines + tankmines set up to kill MAXs when they run in.
Weapons:
LMG: EM6 for medium/long range LA1 Anchor or GD22S for CQC.
Assault Rifle: Reaper DMR for long range. Gauss S for smokelauncher. Carnage AR for CQC.
Carbine: Razor/ACX11 for long range. Gauss S for smokelauncher. GD7F for CQC.
SMG: Cyclone = Armistice, Blitz = Hailstorm; whatever you prefer.
MAX: Mattock for long range, Grinder for most damage and bullets/mag, Hacksaw for full auto.
There is not much horizontal recoil but the vertical recoil is sometimes greater than TR weapons.
You'll fight Connery, west coast of the US. They will have the ping advantage so make sure you keep in mind to play aggressive. Those who peek around the corner first will have the ping in his advantage ( you will not show up on his screen when you can already shoot them). But do keep in mind that bullets will hit you even more when you think you are running behind a building.
I'll be a pidgeonlord at that day so I'll drop some presents when I get to fly above your territory
