On other things, did u notice that there are some other things that DICE added:
 * A91 and M26 Proficiency and Mastery dog tags
 * Added ext mags to RPK74 and heavy barrel for MG36
 * Removed Flash Suppresor on L96 and QBU88
 * Fixed the M320 dog tag that previously showed an M203
 * Added Syndicate dog tag

This is as far as I've seen
