Does anyone know where I can find kit restrictions that would make all the weapons use iron sights?  I've been looking for some mods like that but can't find any.

Non zooming.

You can make a mod that removes the zoom from the guns

Go to:
Ghost Recon - Desert Siege/ Ghost Recon Data/ Mods/ (Origmiss)/ Equip/ then edit the .gun files

change the line(s) that say eg: (oicw)

<ZoomSettings>
      <Zoom>1</Zoom>
      <Zoom>5</Zoom>

to

<ZoomSettings>
      <Zoom>1</Zoom>
      <Zoom>1</Zoom>


Then save the edited file as a new file.. . Then erhm.. . never acctually made a mod myself so this is as long as i know   But i think you need to make a new .kit file and link the "new guns" you made to that kit.

You however not add iron sights to the game as in a 1st person weapon.

Hope that helped some

     I put an Iron Sights kit restriction in the |MP| Mod. It's not tough to do for multiplayer--just edit the gun files like Joka said. IIRC, if you create a new kit restriction for the zoomless guns, it won't work server-side. If you modify the original .gun files (back them up first, of course), and then host, everyone who joins will have iron sights.

There is a WWII mod. all the guns have Iron sights - although the sniper has a tiny tiny zoom but its as close as u can get - standard rifleman etc have good old AA style WWII iron sights

U can get the mod from the *DAMN Mac Downloads page...enjoy
