Airzone Triple Shot - Lanard Shotgun differences?

Is there a definitive answer as to the differences between these two (almost) identical blasters, I've read that the LSG may have a slightly better shell and a slightly wider spring? Does anyone here actually own both of them and care to comment ?

Cheers,

I own both and can tell you the LSG does feel like a slightly better plastic but functionly they are identical (IE: crap untill modded)
In my eyes if you are going to do slight mods, go with the LSG, if doing major mods use either as you need to reenforce the case dramaticly anyway.
