A worse FAMAS, and a good argument for why collecting trophy rifles isn't worth the effort.

A product of old design from before the devs really understood what they had going. Mostly notable for her odd aura which gives colossal accuracy boost, but her stats are kinda eh and you end up with an overall DPS loss still. A fairly meh grenade and basically the sort of sort of thing that would be useful for an early player, except at 21 days in at least, you probably have better already (Hint; You do, you should have AR team by then).

Also known as StG57. Lower DPS than Galil, but has a less awful buff tiles at the stage you will probably use her, because your main tank is probably Sten or something and you'll almost assuredly be running Skorpion that early.

Falls off kinda quickly and has some of the lowest self-DPS among ARs, you won't be using her past the beginning unless you're doing a challenge or really REALLY like her.

The game hates roller delayed rifles apparently.

The new unique equip from the expedition store doesn't help with that, btw. While its stats are excellent (at day…), SIG's base stats are so awful that she's STILL slightly worse than F2000.
