There's just one 8.6mm and it looks more like dressing up the ballistic rig, plus the PLA still as yet make a decision on the new "proper" sniper system, from the calibre to match-grade ammo to low-MOE optics and etc.
The rest are on the export catalogue.
The gatling gun would be quite a something, if the PLA adopt it, from the RHIB boats to the (perhaps) future Z-20...
On the contrary, I'm quite certain that at least two .338 rifle designs are being pursued:
1. The rather crude "XY 8.6mm", which I doubt would be its finalized designation:

2. The yet-unnamed rifle from the Hunan Ordnance Industry Group:

The CS/LM12 and CS/LM5 would be suitable additions to helicopter door mounts or perhaps gun pods on attack variants of the Z-20/9. There is photo evidence that the smaller Gatling gun is in service with their airborne troops.
