Expansion Chamber or gas thru grip for Spyder 2000

[Havok]

Can you put an expansion chamber or a gas through grip on a spyder 2000?? If anyone knows, could you tell me how and what kind of chamber or grip to get.

thanks

I'm not sure if there's any certain type but I'm almost positive that you can.

the spyder 2k has a regulator at the bottomline, so you dont' want an expansion chamber. that will totally deregulate the regulated air. a gas thru grip however, will do i think because it does not have any expansion properties.
