      I do! I got a Mark 4 with the Gunstar frame about a month ago and used it at Supergame MD and a little bit at Skirmish ION.

      I like it and the extra detents seem to be working pretty well. I have run it with a bit of an overbore .688 barrel so far and haven't any issues with barrel breaks. It does seem to be less efficient than my other autococker with the same Nova valve in it running at the same pressure. I think maybe shooting out of the breech instead of the barrel may let some air escape around the ball. the gunstar pneumatics fram also uses some air as well.

      I just got it and didnt have it dialed in when I ran it at Supergame so I want to play another day with it before really trying to see what the efficiency is. I have had a few of the typical Nova quirks that I think I have figured out now. Those were mostly with the pneumatic frame. The peumatic frame is very short and fast but also very light. The trigger was sometimes getting stuck back and Id have to push it forward with my finger. It seems to have been caused by the frontblock having been a little
      loose and rotated a bit which caused the timing rod to drag on the body and stop the trigger from resetting since the return is so light. I adjusted the front block and tightened the banjo bolt so that seems to be fixed.

      The ram body seems to not be loctited and just hand tight so it tends to unscrew a bit after a couple of hoppers. Its probably that way for ease of disassembly but I may put just a bit of loctite there to secure it. Click image for larger version
