View Full Version : Proper springs for co2?

10-19-2008, 05:23 AM
just curious as to what springs are needed for the valve and the hammer to effectively use co2 on a sniper... ideally i'd have a 12g bucket changer going straight into the ASA; would a Madman spring kit have the necessary springs to do this? would appreciate any info; thanks:confused:

Red valve, Blue main seem to be popular

but i think the stock valve spring is plenty hard, but i would have to compare it

On the newer cockers for running direct CO2 you want to replace the LP valve with an old style valve from an early 90's vintage cocker or get one of the new HP specific Palmer's valves.

Direct CO2 works best with a small valve so the hammer can open it right and so that most of the control is due to the springs rather than relying on the pressure on the valve head.

Then go with a hard valve spring and select the hammer spring as required to get the right velocity. Again, using the hard valve spring puts the spring in control of velocity rather than the highly variable pressure from the 12'ie.
