Regualtor?

[RedWidow]

Doesnt a regulator for spyders or low end semis go in the vertical adaptor and does the hose go in the regualtor whats the diffrence between a expansion chamber and a regulator?

[elTwitcho]

Regulator allows you to change the pressure of the gas going into your gun. A regulator also ensures that the same pressure will go into your gun every time. An expansion chamber does none of these things, but it does allow CO2 to expand, thus preventing liquid CO2 from entering your marker.

yep, what he said! The best thing about a reg, is that it give you a much better shot to shot consistency
