Of all the weapons that you've listed, only the ACR Sandfire, G18 Cobra, M67 Frag, and the M9 need new GIFs, and the SG550 Hot Shot is the only one that doesn't have GIFs.

GIF adding procedures state that you should only replace a GIF if it doesn't meet the standards of the CAWiki. Going by that, you should only be replacing the GIFs of the above four stated weapons, and not the entire list.
