Neil,
I store my Tau7 pistol gassed - it will do ca. seventy (70) shots per 12g CO2 caplet, and I don't usually shoot more than twenty (20) shots a week.
So, the pistol sits for up to a month or more gassed, and I have found no problems whatsoever doing this.
I do put a drop of Pellgun oil on the seal of the caplet, and I do wipe a thin film of Pellgun oil on the caplet body.
Have fun & a good Sunday
Best regards
Russ
I keep air in my King Rat and gas in my 2240, never had sealing issues...
If a gun has a cylinder to contain the co2 I leave some gas in.
If it doesn't e.g. Umarex I empty it.
Having said that all co2 guns leak eventually and the above is not always successful.
But the manual for the SMK says leave it gassed as I recall.
Neil,
I have just shot my Tau7 after some five (5) weeks of non-use.
Functioned perfectly, and velocity spot on
Have fun & a good Sunday
Best regards
Russ
