a brand and model plus pic would help.Thanks John M. Finally someone who knows what they are talking about. Do you know how to use it? Like, when I lock my gun up, do I close the valve to keep it air tight, and them before I open it up do I release the valve?
Sorry, this case did not have instructions for this.
i agree definately no go on long term storage.In general, I do not like STORING guns in ANY case for extended periods. However, when putting gun into case, have valve open, close case, close valve, and open again before opening case. If shipping by air, leave valve open during shipment.
usually it doesnt. but it is possible. a sergeant in our unit opened the anpvs4 scope case for my m60 in flight without purging and it damaged the scope enough so it wouldnt turn on. nothing like shattered but it did break the electronics.I have several cases with pressure relief valves on them. The cases can be virtually impossible to open once suction has taken hold. But all of my cases are push button valves. None have a set screw.
I've never known optics to be affected by pressure changes. They are all purged with inert gasses.
