Okay. Is there a mod to have the IW guns in AS?
No special mode. However it's possible in 1.56 Raven Shield and Athena Sword 1.02, with Iron Wrath weapons only mod, which can be available for 1.56 RvS version too. You can find it at Unfinished-games.com. The game also will require some files editing though to make these both work at a time.
