That's the kind of detail that needs to be in a database or Wiki somewhere, even if it's just a half-assed 'history of paintball' type resource. Time's passing us all by, and in 20 years, no one's going to remember details like that. It may not be important in the great scheme of things, but it should still be recorded somewhere.
I still to this day haven't seen one of the Rebline auto kits, nor know how they work. I had an Auto-Trracer for a while (or at least a buddy did) and while it was a bit tempermental, I've always suspected it probably would have worked better with a Rock LPR and HPA.
I've also seen the Chameleon kits, but never had a chance to fool with an intact one. I've been sent parts of the kit before, in both cases by people using them to try to make a semiauto PGP, but that doesn't count.
