What brand are folks running on their PDW and mounting options? Thanks

So on mine...not a LWRC PDW but using their parts I have a magpul MS4 sling. Honestly the MS3 is the better sling and what I would use if I had to buy it again. I have a QD mount on my endplate and another on my foreend. It is an 8" 300 blackout. SBR so close in dimensions to the PDW.
The ability to stow the gun in two point or go to single point is pretty useful when you are using the gun outside of the range.
