So if you take a look at the top of the page, you can see the I:SS promo picture you've probably seen a million times before. The guy on the left carries something that looks to be an MK18, the guy on the right a G3 with a late model wide handguard, and the woman in the back an AK-47.
It kinda gave me the idea to ask about these weapons. The devs could add the AK-47 as an alternative to the AKM on the insurgency side. To stay realistic and diverse, it could be slightly cheaper than the AKM, while having a higher rate of fire but more difficult to control recoil. I think it could make for a nice high skill weapon, and one that doesn't take a lot of effort and time for the devs to model, as they could just make it by modifying the existing AKM model.
As of the G3's wide handguard, I would love to see it in game as I much prefer it over the slim handguard currently in game. I'm thinking maybe the devs could add it as a foregrip option that costs only 1 point, but only offers a very slight recoil improvement over the basic one. Whaddaya think?
