Chamber fan is highly recommended though.
Looking at his build a chamber chain or fan aren't applicable. The chamber is pretty small and there isn't a cleanout.
Packing peanuts are the only thing that makes sense. Airsoft pellets are too small to do much.
If static cling is a problem then either spray/wipe with a laundry antistatic agent or go much more ghetto and just dip it in water (oil, vaseline, paste, mustard, pickle juice ...). Stoping static build up isn't exactly rocket science, besides a bit more mass to the peanut would help.
If the gun is fired with the muzzle higher than the "breach" end then the peanut probably won't go anywhere. Point the gun up before firing to make sure the peanut is all the way back in the chamber.
