Whats the stupidest thing you've done in airsoft? From teching to field. From getting killed by your own grenade to choosing a g3a1/fal for cqb.

I recently took a gun apart, ordered new parts and forgot how to put it back together over a few months waiting for parts. I know there are better stories.
