Meh sorry guys for long wait and that it's not finished but can't be asked atm to work on models anymore, 3DS Max doesn't work properly anymore, even after 3-5 re-installs. I just get every time the error that the file is damaged or something, but o well. I still got atleast the pre-version of it and gonna release that one then.
DL Link = patch-4.MPQ

Note: Just rename the M2 to the weapon you want to change.
