Gun: marushin derringer 8mm
Propelent: i assume propane at one time and now duster (atleast a bottle through it)
Use/Damage: The gun leaked on delivery as i was informed. I assume it was ran on propane causing the gas resevoir in the pistol grip to cause the screws holding it to loosen. Loctite teflon tape and putting the screw back in now holds it in tight and works flawlessly.
Gun: KJW mk1 carbine
ropane before i owned it, now runs on duster (3 or 4 cans now)
Use/Damage: plastic hopup unit in it sucks and cracks easily. Fixed with a very hard to find metal hopup. Gun works flawlessly now.
