Great for tinkerers is right. What about outlaw ballers that shoot 500 rounds a day or so? It works there too. While I don't think it would do much for most of the agglets I see a distinct use for this to help with those who play outlaw rec. No more "mommy take me to ______ for CO2". Same demographic aim as the Tippman propane thing. Considering Tippmans new marker we saw pictures of there might be a strong market, I wonder how that thing is going to work with CO2.
