"I purchased this, in advance, hoping to get a broken AR-15 variant, and use the parts to resurrect my long dead JG s-system, or JG AK. I had to wait a week for its arrival, during which I kept checking the package information on UPS. It was under six pounds, so I assumed that the broken gun I had bought was an MP5. When it finally arrived, I was extremely excited to open it up. I opened it up, and was amazed. I got a JG Commando, http://www.airsoftmegastore.com/1905-jg-airsoft-m4-commando-metal-gearbox-aeg-rifle-w-tightbore-barrel.aspx. Awesome little gun, but I will save that for its review. What's more, the only thing they salvaged out of the box, was the battery. I checked:
Motor-great, pulled my JG M16s piston faster than its stock motor
Inner Barrel- Fully intact, hop-up still in place
Stock- fully intact
Gearbox- piston locked back
I took apart the gun, got to the gearbox, unlocked the piston, and what do you know... The gun was fully functioning.
Charger was there, handbook, cleaning rod, only thing gone was the battery.
A $130 gun for $35.... This was an excellent buy, and a thrilling ride all the way through."
