I'm a little late to add my 2 cents here but I'm going to do it anyway.
I have this gun and I must say out of the box it fired over 400fps. I had to replace the piston and the piston head because it over powered the cheap plastic parts. The other problem was the body breaking down where the holes are for the pins and screws. Having fixed the internals this gun rocks, it's a great performing gun and your right it is very easy to strip it down. I really need to replace the body. Do any of you know if another companies body will fit?
