Anybody been killed by this weapon? I've been on a few servers where I've been killed by this, but have no idea what it is, and how you obtain it.

Is it an admin weapon?

Its an underbelly attachment only.

Thanks Sient! So its a nade launcher - that explains the multiple / rapid kills I keep seeing.

Yes it's the Russian equivalent of the M320. I was properly named in one of the later patches. Previously, getting killed by it showed as the M320.
