whats needed to keep moisture out of my pcp gun?

[MacGyver]

I have thought a lot about switching to dry nitrogen so that I don't have to worry about things when I put them in storage and of course have my compressors for backup. I would be interested in hearing any words of wisdom you have on the subject.

It sure would be nice if you could pull a vacuum on a PCP like you do an HVAC system prior to filling. That would remove all moisture, but I don't think that would work well on the other components that aren't designed to hold pressure in the opposite direction. LOL

so would one of those be more or less effective than modding the tampon ones? id prefer not to spend much more than $100 on this sticky filter situation because after i get a scope im creeping up on "i should have just bought a nice browning over under"
