I am bit late, perhaps, but I think we have both M76 and M77 LMG in game. EZ9 & EZ40 - Not so popular Zastava's pistols in 9mm Para and. M91 & M91 N - Not only a copy of SVD, great DMR and also avalible in more sceletonized version. The high tier rifle in Zastava's inventory and something that AIMNAS armory needs also. Adopted by few agencies and special forces. M21 - Still AK, but improved, also avalible with rails.
It's great quality Zastava product and also a great addition to somehow US-RU monopolized.
This weapon appears in Far Cry 3 & 4 game. To incease chance of appearing in weapon market rifle is avalible in two 12,7mm calibers. Zastava react to answer of the screm of need and developed bolt action M93. M93 - Need of AMR appears also in Serbia. M80 & M90 - NATO ammo compatible AK, one of many Zastava's ideas to earn money and one of few non russian 5.56 AKs. Great Zastava rifle and revive for forgotten calibre. Rifle widely used in Yugoslavia Civil War. Later when they starts to produce licensed AK, suddenly many of former german small arms it appers in middle east and africa. Yugols after WW2 gets many of German 7.92mm ammo, and weapons for it. M76 - Interesting DMR made from AK that uses 7,92x57. M77 + AB2 + B1 - Just a battle rifle made from AK, also avalibe with heavy barrel for LMG. Bulid on with cover from AK, avalibe also in MP5K and SAF-K dimensions. Master FLG & FLG-K - Another less popular SMG. I really hope it convince you to some of them. Now it's all in one place together and more like "Hey, look at dat gan, it's really worth adding". Szczelec wrote on Sat, 11:46 I decided heavly expand "why add" desription to give weapons more chance under eye of smeagol.
Widely used in WW2 and by US Special Forces in Wietnam. Sten MK.2S (9x19) - Cheap well known Sten with integral suppresor. This reliable SMG saw use in Vietnam and even Falklands islands. 元4A1 (9x19) - Integrally supresed Sterling SMG. Then K model is abnormally short ranged, unaccurace, uncontrolable and even more unrealiable sick's man idea with completly no real field purpose that utilize barrel about twice long as 7.62x51 cartidge. MC-51K (7,62x51) - If 8,3' barrel MC-51 was ridiculous with it's hard recoil and unrealibity. AW50 (12,7x99) - AW bolt action rifle scaled up for 12,7mm.
