Its obtainable but you have to be careful where you are getting it. I once went to a machine gun shoot in Slovakia back in 2015 where people brought their Full autos.
A guy brought his DSK that was from a T55 tank and he converted with a ground mount.
Another guy came from Albania and was selling ammunition that was either Chinese or Albanian made from the 70s and 80s.
Lets just say.......his poor DSk needed extensive work.
