I am the original owner of this unicorn. Got it straight from Smart Parts back in 1999. These were the the first Evolutions to introduce the center feed bodies that followed with the new post 2000 bodies. I have another one that I used on the field (number 17). Number 6 was only gassed up to time it. I did put a roller sear in it, however.
I still think Evolutions were the best paintball markers ever made.
