CYMA Full Metal AK AKM Airsoft AEG Rifle (Model: Imitation Wood / Add 9.6v NiMH Battery + Charger)

"Just barely a week after I bought this gun I took it out to my local field. Within the first few mags through the gun my piston stripped, and my spur gear had a chipped tooth. After replacing those parts then came a bunch of problems with the compression as well. Even with that the selector switch for me never seems to line up properly when I put the gearbox back together. I'm hoping this is just one lemon out of the bunch, but all I know is that I am not buying another CYMA.
