For Ars these 3 ARs to go for ICR, Maddox and Vepr for attachments it's all personal preference but I like to run stock elo fast mags in the Vepr and Maddox the ICR is the best gun in game so anything on that gun would work hope this helped

Awesome and what about smg's and snipers?

I don't snipe too much but the snipers got a buff so outlaw paladin all very good, even SMGs got a buff their pretty poor but the spitfire is not too bad and the saug 9mm with operator mod dual wield is pretty decent

here's mine:

Primary:
Vapr-XKG
- Elo
- Fast Mags
- Rapid Fire
- Suppressor

Gear: Acoustic Sesnor

Perk 1: Scav
Perk 2: Leightweight
Perk 3: Dead Silence

SMG:
GKS
- Relax
- Grip
- Long Barrel
- Extended Mags

< perks & everythin else > same as class one

I have to many to show, maybe I'll screenshot and upload if you're interesting in knowing.

Depends what mode
Vapr and Maddox are both really good.
Vapr i use Stock 1 and 2 and Rapid fire if you can
Maddox i use Quickdraw 1 and 2 and stock
Equipment that is good is cosmec device or stimshot for a fast paced map, Acoustic senser is good but i think mostly for search imo.
Also acr with grip 1 and 2 and quickdraw with the thermal site is really good, basically no recoil

For snipers I use the Palatin with the stabilizer, sight reloader, and high caliber with scavanger, lightweight, gun ho, and dead silence .. pretty class for quick scoping

If you play hardcore try out the swordfish:

Primary: Swordfish
Reflex
Quickdraw
Suppressor
Hybridmags (optional)

Perks:
Engineer
Gung-Ho
Team Link
