Converted my Sig MCX to HPA, works much better. Question is , can I leave the tank on the gun while filling it ? Or is it better to remove it then reattach each time. It is the air venturi tank with the 1100 psi regulator. Also, is it cool to leave the tank attached, with pressure, while I'm not shooting ? I dunno if it's too hard on the seals maybe?
Thanks guys
