Anyone make a conversion kit to change a 9mm MP5 into it's 10mm or .40S&W counter parts? The magazine well needs to be bigger and a new magazine needs to be made since the .40 and 10mm rounds are so much bigger. Just wondered if anyone made one. It would be a cool cosmetic change.

There is one guy on Airsoft Retreat that makes custom MP5-10 Mags 70 dollars per mag though...
