    Default HK USC to UMP

    I'm in the process of converting my USC into a UMP clone. Just got it back today from Sean at CDI. He does great work, highly recommended! I had him mill out the 5 UMP vents as well as open up the receiver to accept the double stack magazines. Functionality is great! Now onto the Form 1 to SBR it.

    I did this to my USC in 2010 and never looked back. Great mod and a super fun gun to shoot!
