Update Nov 19 : Version 1.6
----------------------------
Fixed the sound not working while you had the silencer equipped. But I ran into a weird crash with the G.E.C.K and in game which required me to remove the mods for the original riot shotgun. So I modified the stats a little(increased the damage, clip size, reduced spread a little) to make up for it. I don't know whats going on but the game crashes when all 3 mods are equipped, and if I try to edit the model for "MODS 1-2-3", the G.E.C.K. crashes.

Update Nov 18 : Version 1.5
----------------------------
This Mod adds an automatic version of the Riot Shotgun.
As well as add 3 mods for it(Silencer, Clip Increase, Spread Reduction). Unfortunately the only model change when applying the mods is the silencer.

I also changed the Riot Shotgun's drum to a clip, and left the automatic Riot Shotgun with the drum so it was easier to distinguish, plus it adds a little visual variance(I wish I could do more). I've also increased the damage of the automatic version, as well as reduced the spread a little bit.

You should be able to loot either gun like normal, as well as purchase them and their mods at various Vendors.
