At this moment there is only one pickup with mounted MG for all factions. And it has SPMG MG, which is NATO's MG.
It would be nice to have pickups with different mounted MGs, e. g.:

• with Navid and/or Minigun MG for CSAT
• with LIM-85 for Syndikat
• with SA-77 for SFIA and Tura

etc.
If you add such pickups, don't use existing hand MGs, as in this case, most likely, zeroing won't work -- https://feedback.bistudio.com/T170100
