Here you go: http://en.wikipedia.org/wiki/List_of_modern_Russian_small_arms
Only Guns on list that’s in game (according to the item browser and memory) is the Tokarev pistol (TT-30), Saiga-12, Mosin–Nagant (1891/30, M44), SKS, Dragunov sniper rifle (not in main (stock) game, it’s a part of Icecoon’s semi-futuristic weapons pack, a variant of it made by Clearwater Arms chambered in .308, you could still add the original Dragunov if you want with the 7.62x54mmR), AK-47, RPG-7, PPSH-41 (not on list, likely cause it’s not Modern)
