i imagin if you were to break down your gun right after playing with it in the wet and you dried it out and re lubed it it would work okay. water seems like it would be way less detrimental to a gun compared to dirt, dust and grit would jam up your motor and chew up your internals.
Precisely. If you treat it like you would any real firearm (like, say an AR15) and keep it well cleaned and such, nothing to worry about.
For those who are saying rust will form....typically in rust-prone environments (like, tropical islands like Guam, and places near the ocean like Florida....) your gun will rust no matter what.
I did tear them down, clean and re-lube after those ops. But then again, the first 3 days after a decent op I spend cleaning all my equipment to make sure I am ready to go at a moment's notice. No matter what environment I am in, I always make sure my guns are clean (both airsoft and real). A dirty gun is an unhappy gun, and will do nothing but give you grief.
