Lucky Stage 1 & 2
What size tank you got, at what pressure, and how many shots per tank do you get? I been getting about 600-ish out of a 3000psi 0.8L tank from a stock Ion. Just fitted QEV and lucky stage 2 to hopefully get more.
My recomendation is.....
Get Lucky Stage 1 and 2 and a QEV.
Stage 1 = Firing Bolt
Stage 2 = Firing Can
When fitted adjust your dwell. (turn it right down, adjust up one at a time until gun dry-fires without drop-off, then put it up a few clicks, and then try it with some paint in to be sure.)
This mod and adjustment should improve your efficiency by about 30% I'm told.
