Crytek or Saber seem to have used a broken, unfinished version of the SCAR Model in the Remaster on all plattforms. Until this is fixed, I have restored the old (finished, more detailed) model for the Remaster.
Alternate download, makes the console version SCAR that's left in the game files accessible and fixes it's texture. Drop "zz_ModernSCAR.pak" into your "Game" folder to use.
