Yeah have done, that's not the thing. It's a "Lefty HP valve. They cost £26.50 + vat".
Fair enough it's an HP valve but I shouldn't have to pay £30 over and above the money for the max flo just to use c02, it's not like the max flo wasn't designed for any c02 use
If it gets the damn thing shooting then I suppose I'll have to do it
Thanks again.
