So, when I told a friend about what I was doing, and the adding of the Saiga12k to the SSG slot, they suggested that i add a "KS-23" and then added on "And make it fire Explosive shells!" So here it is. As you can see, it's OP-ish, the power is balanced out by the small Magazine, and small ammo supply in general (28 shells WITH a backpack) Oh, and a slow reload and recoil greater then most other weapons in this "Modded mod". Oh yeah, and you have to pick up "parts" to make this weapon, too.
Due to a lack of suitable sprites, I decided that this KS-23 is "Modernized", for some odd reason.
