I never liked how chunky the MWO version was, so I slimmed it up a bit making it much taller but keep the volume about the same.
Furthermore, I redid several joint to give the mech the look of something that is more flexible. The mech is supposed to be able to turn its arms around and fire to the rear and able to walk up much steeper inclines than other mechs thanks to its joints being extra flexible. I also made the SRM-4 look like a cylinder for a revolver, as it both looks more like the original artwork but also fits the name. Finally, I fitted a mohawk to it following the TRO art.
I did a bunch of variants.
