ok. I ordered 4 high flow valves from wgc. I then sent the valves and the mags to airsoft atlanta to get them assembled and installed. I get them back and 3 of the 4 work. so i send the other one back. It gets fixed and then by the time it gets to me it leaked again. So then i waited to get some money to buy some new ones, and this time i asked wgc to assemble them. in the meantime i play with the other three. After one game, two started leaking. Then i get some money and order 3 assembled valves form wgc. I get them before a game, so rather than ship them out again, i installed them. When i installed them i used the silicone spray you get whn u order the gas package from airsoft atlanta...the one with two cans, and bag of bb's, and silicone spray. Then the next day at the game..they started to leak..now 2/4 work.But my question is do i need to have them if im gonna shoot top gas? i have the slide and spring upgrade, but do i need the valves?

Oh by the way when i put 134a or top it leaks.

edit: the leaks are where the mag meets the valve on the back of the mag.
