IG90 (Infiltrationsgevär = Infiltration Rifle) is an adaptive rifle specifically made for the infiltration and spec ops squads. Standard caliber is .30, but can easily be turned into a .50 Beowulf by changing the upper receiver and barrel. It comes in three preset versions; IG90a, which is basically the rifle itself and is merely used for training purposes. IG90b has weaver rails, a red dot scope and a front grip, as well as a suppressor adapter. IG90c is the SOPMOD version, with magwell grip, ergonomic front grip, laser sight, LED flashlight, suppressor adapter, additional rails and hybrid sights.
