Whereas the lower receiver is where the stock fits to the body... and one of the principle stress points... It would seem to me that using real bodies both upper and lower.. and modifying to fit the Mechbox and cylinder sets into these bodies makes economic sense... I suspect however that there may be trademark and other proprietary issues.
Anyway.... here we are chatting about how to make this thing better when it is already so much better than the typical gun....
The uppers seem to be the first to go on PTWs... atleast from what I've read/seen.
The only thing I'd want to be improved, is a stronger receiver set...
