I have over 4000 hrs in the game and know the difference between a SVAL/VSS shooting at me and something bigger - I also went on to test it with my friend by standing 80-100metres from her and getting her to shoot at me with a unsilenced Mosin - give it a go and see what you think. In addition, live whilst streaming, TRMZ was being shot at by an unsuppressed DMR which sounded suppressed - you can watch it on his stream. As the other fella said, he ended up teaming with the guy who confirmed it wasn't suppressed. Finally, I was wearing a plate and a helmet and got unconned with one hit from distance - no VSS or SVAL can do that plus I didn't even realise I was being shot at as the sound seemed absolutely miles away - there definitely is an issue - but try it for yourself - get someone to shoot at you unsuppressed from 100 metres or more with a big rifle - it is very weird and cannot be right.
