Yes my answer was very specific and just the difference. I would imagine they either run larger ports and or heavier hammers and springs. If people modded Daystates like they do other rifles like the marauder we might know the answers. For all I know my Daystate wolverine can make the same power by just opening the transfer port up or installing a heavier spring. If they all have the same porting then a spring change and maybe poppet spring change and you should be able to get that same power.
