Mrod pressure retention?

[uncle paulie]

Just wondering how long an Mrod can be normally stored with enough pressure ready for a couple quick shots?

U. P. theoretically, a very long time if, al the valve innards and seals are in A-1 condition and seat/seal perfectly, likewise with the reservoir/tube and fill connector and gage fittings.

Some non-airgun studies of synthetic and natural seal materials (compressor industry stuff) shows that permeability or the resistance to gases or air leaking through the seal materials is where most static pressure loss comes from over long periods of time.
