WTS/WTT OR HK USC Converted to UMP

[mr11b]

SOLD This is a new in box HK USC converted to an UMP. Minus the barrel length, this is about as close to a factory UMP as it gets. It is a complete conversion done by Tom Bostic of Tommy Built Tactical. Tommy Built is the leading HK conversion smith in the country. This is not a bolt on kit, or grease gun conversion. All the details will be listed below. I was going to SBR it, however I decided to move on from this project for another one. Considering it is my only .45 it didn't make the cut. For a complete conversion the only thing left to be done is chopping the barrel and the tax stamp.

I am asking $3000, with an option of up $1000 in trade. I have all original receipts for parts and work that far exceed the listed price. My trade considerations will be listed below with the details. Please PM me with any trade offers. Also feel free to PM me with any additional photo requests or questions. Thank you for looking!

Tom Bostic does very exceptional work. I just bought one of his T36 receivers. I have a question. Why did you not have Tom convert a UMP lower so you could run 30 mags?

It is converted, I just had purchased the 25 round magazines prior. I listed it in the details of the work that was done, its the last line. I had him literally do everything, which is in the paper work, minus a NFA engraving since I hadn't gone that route yet. Congrats on the T36, that will be one sweet machine once your finished with it.
