    USC to UMP conversion

    Thought I might get one of these going for my UMP conversion. It is a pretty simple job though compared to making an SL8 a g36.



    Anyways, start with your USC Carbine-





    Buy a UMP lower, stock, and stock block-





    Enlarge these hooks on the UMP lower with a round file-





    Attach the stock to the stock block with a stock axle pin-






    And throw it all together-













    I submitted my form 1s 12/27/11 so it should be another 5 months or so before that comes back and I can finish the job, but oh well. Now all I need is a short barrel, vents cut in the forearm, and a UMP magazine (cant find one anywhere so I am stuck using the USC mags for now). If anyone has a hookup on a UMP .45 mag please let me know!

      Fuck that shit. $205 for a magazine is just wrong.


      I called HDPS and he said that everyone is out of them everywhere because HK just hasnt shipped them out yet. Said it should be another couple of months. I can wait.

          Well, let me see here.

          Gun- $1100
          Lower- $400
          Stock/block- $300
          Tax stamp- $200
          Barrel- $250
          Vent cuts- $50

          Should cost about $2300 to complete.

          Fuck, adding up the cost of building guns is depressing.

              what amazes me is there is 15 bids on it and it started at a penny.

                Alright I made some progress. Sent the gun to Ed at HDPS to have the vents in the front end milled and have the mag well milled out to accept UMP mags.

                And yes, I finally rustled one up (but just one) for way too much money.

                Tonight I popped the barrel out so now I am just waiting on the ATF so I can order a short barrel and slap it together!

















                I will get all the parts together this weekend and take a photo of it all sans barrel so you can get a pretty good idea of what it will look like completed!

                  Looks a hell of a lot better than what it started as.

                  BTw the whole HK magazine thing sucks our local PD ordered some for their MP5's and it took almost 8 months to get them, sometimes they are just slow as fuck shipping things out.

                    Alright I threw it all together for a nice photo op. Now all I need is for the ATF to mail me my stamp and I will be good to go!

                            Not very versed in HK stuff does the butt stock fold? It looks pretty ridged but not real sure at the same time there could be a pin there.

                              Yes the stock does fold. There is a small button you press.


                              And thanks for the comments guys!
