Here is my HK UMP Clone with Gemtech 45 acp Suppressor. It was built with all New HK Parts including a New HK 45 acp barrel. It is super accurate and the suppressor is very quiet.
What do you have into it dollar wise? Looks great.
I built this UMP Clone back in July 2007. I traded a NIB Bushmaster Pre-Ban Carbine with a 11.5" barrel and the long FH for a NIB HK USC Rifle. I think I had $350-$400.00 into the BM Carbine. I bought it as a dealer in the mid 80s so I paid dealer price. I had 3 of those Excellent Pre-Ban BM Carbines. I bought an real HK Factory Rebuilt UMP with a New Barrel for $700.00. The C3 dealer I bought the UMP from stripped off all of the parts from the receiver, cut it up and sent the proper paper work back to the ATF. I kept the New HK UMP Barrel and the one HK UMP magazine and sold the remaining parts to a member in AR15 for $700.00 plus shipping. So I got the barrel and magazine for free. Looking at my saved documentation the KAC Grip, HK UMP Butt Stock, and the HK UMP FBI Trigger Group, and a quick release barrel pin cost me a total of $400.00. I cannot remember and I do not have that documentation on what I paid Ed Montana of HDPS for the build.
A C3 dealer in TX got stuck with 5 Gemtech UMP Suppressors when a PD ordered 5 suppressed HK UMPs. He bought the 5 Suppressors and ordered 5 HK UMPs but after a year HK failed to deliver any UMPs and the PD canceled the order and bought 5 suppressed Colt M4s. The dealer sold me the Gemtech for $725.00 shipped to my C3 dealer. He told me that was his dealer price on the UMP Suppressor. I don’t know if he was telling me the truth but I do know that $725.00 was way below retail.
Yeah, I have one done too.
Basically bought a USC, then bought a UMP for donor parts, then had Tactical Excellence do the conversion (which was almost the cost of another rifle) and was able to have one firearm for the price of three.
The things we HK enthusiasts do to have something close to a correct HK firearm because lord knows HK will never be able to import one like this. Fortunately I was able to sell the extra USC and UMP parts which pretty much offset the cost of the actual build (eventually).
I remember the UMP suppressor was expensive and that sounds about right for my dealer price back then, but damn sure glad I grabbed one because you can’t really find them now.
The UMP was a pipe dream since I first read about it in Soldier of Fortune in the 90s, never ever thought I’d have a setup like this one. And the opportunity to try and do it now is pretty much gone, especially if you want things like a factory HK barrel.
Most people are rolling Top Notch parts or HDPS parts.
You Have a Great Looking UMP!
I too have an all German UMP with both .40S&W and .45ACP bolts and barrels. They are more expensive than they used to be but you can still find deals occasionally on Gun Broker and the forums. I picked up my German .45ACP Barrel for $250 a few months ago and last year lucked into a German .40S&W barrel, Tom Bostic converted bolt, and 4 mags for $450 on Gun Broker. But gone are the days of getting good deals from retailers. HKParts is selling pulled German .45ACP Barrels for something crazy like $800.
I really enjoy shooting mine, it’s very ergonomic and feels much higher quality than my old CZ scorpion. I prefer mine in .40S&W.
How do you guys like the Gemtech suppressor? I’m waiting on my stamp for one.
I like it, but it’s not like there are lots of options. I think the only other UMP suppressor is made by B&T and is technically a “premay” dealer sample.
The gemtech performs well but mounting isn’t as quick and easy as say a MP5. But that is going to be true of any suppressor designed to mount on a UMP.
B&T USA makes a transferable UMP suppressor now. I was planning on going with that but got a great deal on the Gemtech.
The gemtech is a super built FA rated suppressor.
Sweet, I wish HK could figure out how to make / sell stuff like that here to the US these days, but there probably isn’t a viable business case for it.
Agree with you, UMP is probably the lowest priority for H&K. I love mine but still prefer my MP5.
Would love to see them update the MR556/762, introduce a full size SP5K, and sell a Semi G36. They would all sell like hot cakes under $3,000. Probably a pipe dream.
I read mixed reviews about the flange mounting system. On my Tom Bostic conversion, I went with a 16x1 LH threaded barrel (I used a USC 16” barrel and had it cut down to 8”). Only issue is the flash hider comes loose on firing. I am waiting on a Ti-rant 45M in NFA jail. That may have been dumb as well, because guys on HK Pro are seeing large POI shifts with that combo. Anyhow, I love my UMP conversion. It is by far my favorite PCC.
I went with a direct thread option on my UMP as well. The Octane 45 HD is an excellent option for these as well.
The flange is just clumsy and I worry how it will wear over time.
I get that HK lives to be innovative and are more interested in previously unimagined designs than being practical, but sometimes they need to realize things like 3 lug mounts are it and stop trying to reinvent the wheel.
The MP5 suppressor mounting system is the best one I’ve ever used on anything. Thread mounts walk, it’s been true since the Ingram M-10. The Uzi had a nice locking mount but it wasn’t exactly the fastest thing you’ve ever seen.
I’m jealous of these UMP’s, but unless people start selling them fully assembled with all the conversions done and such, I’ll probably never have one.
Those days are gone. The USC is no longer in production or imported and finding UMP parts, especially factory barrels that can no longer be imported, is even more difficult than when we did these builds a decade and a half ago.
Trying to do a UMP build today would probably cost twice as much and we probably paid the price of three firearms to accomplish one. There is an Omega clone but I’m pretty sure that’s a Todd / Wendy / Wade Bailey cutout company operation.
Exactly my point. May take a look at the new offering from LWRC if it gets decent reviews.
Of course, then I’ll just need a pile of UMP mags…
USCs just went back into production: https://hk-usa.com/hk-models/usc/
I bought two last summer, and at the NRA show, the reps said they’re still being imported. As you point out though, parts will eventually dry up (especially UMP demilled kits). The UMP will probably go away before the MP5 will ironically.
If you call HK USA, they will order them direct from Germany for you. I bought ten UMP 9 magazines that way. It took 3-4 months, but they still did it.
The Bailey’s released their own receiver (The Gideon Shadow) and that has sent UMP kits and parts skyrocketing in price.
