Many thanks to you all.

I don't understand why Airsoft owners use so much silicone in their guns. I've seen them using it as a general cleaner, lubricating the slide rails with it, even spraying it into the trigger group.

And yet many Airsoft pistols are identical to co2 air pistols made by the same manufacturer, the only difference that I can see being that they use green gas.

Everything that I have read about Airsoft from owners and makers insists that only silicone oil only should be used on their guns.

I'm beginning to wonder why their guns don't seize up. But nobody has ever explained this to me. I well remember the bloke from Theoben warning about the use of this stuff on this forum years ago. Yet Airsoft experience would seem to prove him wrong.

If their guns did gall they wouldn't use it. And makers wouldn't insist on owners using it.
