This issue is still present after todays patch.
I know today was supposed to fix some network related stuff but still having these issues.

I can confirm these network issues are still present in todays patch Version 0.9.5.49.

So it's 2019 and this request from 2013/2015 is still relevant.
This should still be a consideration for implementation in my opinion as milsim and vanilla players alike would benefit from this like crazy.
It's somewhat annoying if I'm honest that an Alien DLC takes precedent over something so small but yet so big for the wider community, this feature would effect how people interact with your product ArmA 3 for the better and I think it's crazy that feedback that goes as far back as 2013 when the game was in Alpha still is overlooked.

Just double checked and this also occurs with the non sawed off version of the Kozlice 12G.

Good to hear i look forward to more testing then :)
