Im building a UMP clone and I need one so I can have Tommy cut and thread it Send me a message, im in FL

I am in the process of building a 45 UMP clone from Tommy. I bought a kit from hkparts and I am really in the gathering stage so far. I want it to be a pistol in 45 with a 3 lug. I thought that if i got the HDPS threaded 8 inch and the silencerco adapter (pics) it would be ok. Tommy said that...

Hi everyone, I wanted to post this information for some time and haven't had the opportunity to do so but better late than never. In brief, I had a locally recommended engraver attempt to put my approved Form I mandated engraving on my USC/UMP with the name of my trust and locality. What I...

Hi everyone, I recently finished putting together a UMP clone in .45 using the Omega Gideon Shadow receiver. I took it out today for some first shots, put a mag in, charged it and got a click and no bang. When I went to cycle the gun, it was completely locked up, and had to be mortared to clear...

Posted this for sale complete in the pistol for sale section, and have been recommended to just part her out for a quicker sale so that is what I'm doing. This is my UMP build that I have only had for a couple of months, I'm dissecting her to help pay for some Dental Bullsh*t. Everything is...

Selling my UMP build that I have only had for a couple months to help pay for some Dental Bullsh*t. Everything is German except for the Gideon Shadow receiver. EXCELLENT condition, no scratches, only 450 rounds fired through it. No malfunctions. Literally looks like it is brand new. Well...

SOLD This conversion started life as a 2018 mfg (date code: BI) black USC 45, 100 rounds were put through it in the factory configuration to ensure function. The gun was then sent to Tommybuilt to be converted to a UMP using the rear section fuse method, this is not a "stock block" conversion...

I have been searching for a USC or UMP .45 Bolt Carrier Group and barrel for a little while now with no luck, so I figured I would just buy a whole parts kit and sell what I don't need or hold on to some parts for when I decide to go the SBR route. Yes, I know HKparts has them in stock for...

Is there any difference in the bolts for a SA USC and a FA UMP aside from the bolt height on one side and the tungsten filling? I would assume there is some kind of area that trips the release lever on the FA bolt, where that doesnt exist on a SA bolt...but I cant find photos that look...

Up for grabs, US made 9mm USC/UMP conversion kit. I am the second owner but it looks like it hasn't seen more that 50 rounds. Comes with 2 mags, barrel and bolt. if you need barrel pin just let me know. price is $525 + shipping.

This is my first post here. I looked for a similar post on here, but couldn't find any, so I apologize if this has already been discussed. For all those that have a UMP build in 9mm, where do you guys find magazines for it? I have only been able to find HK factory mags, which I have 2 of. Is...

New member here, just acquired my first USC, and going over the plethora of upgrade options available for the weapon. It seems the only way to do the short barrel(besides the $200 taxtheftstamp and 9 month wait) as of right now would be to remove the stock/grip combo that comes with it, and...

I am looking to sell some extra UMP parts that I was going to use for a conversion. The parts include one complete UMP navy lower, one demilled UMP rear stub, and one UMP folding stock. The lower is in good shape, but has definitely been used. All the pictogram markings are still clearly...

Hello and glad to have finally joined. I am looking to purchase a USC to add to my HK collection. I was just scammed over at Armslist, but was lucky enough to not lose any money. If anyone knows of someone selling one, please tell me. Thanks a lot. Walker Martin HK91 HK USP Compact

New Question, who has experience with a USC-ump conversion? Specifically the rear section of a real ump fusion/welded to the receiver of a USC with the receiver redone to look like a real ump. Pros? Cons? Same question for a stock block? Pros? Cons? So what is everyone's experience with the...
