I've done some work to it since. I've added a small expantion chanber and done some custom engraveing. this is only 1 of 3 I have (2 of which are operational). I plan to put up some other pics of both when I get the chance.
I was thinking about adding in a dual bottle adaptor the to the one shown but I'm not sure how to do that with the expantion chamber, and place a 6 pound CO2 tank (you know a converted nitro tank the BIG one they dont realy make anymore once I find one lol).
the last thing I planed adding was a HALO or some type of force feed system i think it would compliment the Starfire bolt inside nicely.
