As requested.
Unfortunatly I also have a UMP to Skorpion mod on the REZ files and I cannot get rid of it since I do not have a clean REZ file of M_SMG and T_SMG so you might have to get REZ inject to inject the LTB files in which is in the Injection!.rar. But if you don't care about the UMP then go ahead and download the P90 to PP19.rar.
For Injection!.rar: Virustotal. MD5: 8de0301317c52df7bfc851022fd8c0cc
For P90 to PP19.rar: Virustotal. MD5: 06cb9b44a56d5cbd6b647791506c50e8
For some reason virscan is not working for me so I cannot get 2.
