The machine shop JMJ was based out of is Moyer Machine (http://www.moyermachine.com/)
. They are still around, but I don't know if John is still there, and they have expressly stated that they are no longer interested doing paintball work. The design for the Highlander was owned by Anthony Navarro of Action Pursuit Games which is now Colorado Shooting Sports. The design of the Immortal belongs to TargetIndy
of On Target Entertainment.
Also, not sure if you saw this one, but I'm pretty sure neither Ruler_Mark or Elia got permission before making this.
