Yeah, so as the title says im a bit confused and having trouble converting my r6b sens to pubg, im using monitor distance and everything I just don't understand if I should be converting my Acog sens to 2x and so on or my ADS sens? 

The ADS and ACOG in R6 are completely disconnected from each other even though they use the same sensitivity.

So it depends on if you like the way both of them feel in R6 (if so convert ADS up to 2X and use ACOG for the rest), or if you prefer one of them. If so convert this to all aims.

thank you!
