UMP bullet button for USC conversion?

[Steve1968LS2]

Ok, have a Cali USC.. hate the stock.

Was going to do the HERA stock (non-folding) but there seems to be debate over the 922r aspect.

So, looking at doing the HDPS UMP full conversion (again, no folding stock).. does someone make a bullet button that will work with the UMP lower or will the bullet button in my USC work in the UMP and I just need to transfer it?

They will ship me the 25rnd UMP mag kits and I will make my own blocks to take them to 10-rnd.

thoughts, ideas, suggestions??

Thanks

Email Peter (Radd). He has (or can fabricate) the UMP mag lock. The USC mag lock is too small width-wise. You'd need to shim it. I got mine from Peter directly and he charged me the same price as the USC lock.

Not sure why you gave up on the HERA. Regardless of 922(r) issues, you're still going to have the same issues with the conversion you're just going to be out much more money. Trigger, floorplate, and follower is what you'll need on the UMP conversion. So if you're gonna spend the money, why not buy the HERA stock and buy those parts just in case. It would save you about $1000 going that route.

The UMP kit from HDPS comes with all the compliance parts like the floor plates, followers (two mag kits) and when I go out of state I can still go 25 rnd double-stacks.

Oh the HERA deal I hear two things.. on is that it doesn't trigger 922r and the other is that it does and nobody makes enough compliance parts to fix the 922r part. I don't see what you mean about buying the floorplace and follower with the HERA deal since they don't work with the USC mags.

And yea, I can see where paying an extra $1000 for the UMP just to get the double stack mag capacity is a bit silly here in CA, but I shoot in NV quite a bit and don't plan on living here forever.

$600 one way.. $1600 the other..

What's your thought on the HERA 922r deal? And yea, I know the ATF really doesn't chase it and they really only use it as an add on deal (I have a Benelli M4 so I know that drill)

922r only applies to making (or remaking) an otherwise "banned" foreign "assault weapon. However, no matter what you do here in CA, by the time you pin the stock and have a tool only removal system for the magazine, any only have 10 rd mags for it, it is - by definition - no longer an assault rifle bearing ANY resemblance to the foreign assault rifle it once was. In short - don't worry about 922r in CA. Once you cover CA law, you have more than covered 922r

[Steve1968LS2]

That's my point.. this is no "banned" USC rifle.. and there is no USC assault rifle to begin with. lol

Now I'm just deciding if it's worth a grand to do the whole UMP deal and have the future ability to run double stack mags and other fun stuff.. the 20 rnd USC mags are sorta goofy.

What someone needs to do is make a double stack that narrows down at the end into a single stack to work in the USC..

If you do the full conversion you won't regret it. I did the UMP 9mm conversion about 4 years ago and it's still my favorite gun to shoot to this day.

I'm jealous you were able to do the 9mm conversion, those parts seem to be hen teeth rare at this point. I have a 'as full as legally possible' ump conversion and it is AWESOME. Do it right the first time!

Ok, if I'm shooting it in CA (so stuck with 10rnds) then what other benefit is there to the full UMP conversion? How would it shoot better than the USC with the HERA stock and grip?

There's absolutely no benefit other than looks. If you want a gun that looks like a UMP, you do the conversion. You'd be spending a lot of money to shoot the same caliber as the USC shoots just to have a pistol grip and to be able to convert your mags back to high caps out of state. I actually own both a USC and a UMP conversion and the only reason I converted my black UMP 4 years ago was to shoot a cheaper 9mm round on top of having the UMP look. Back then the 9mm and .40S&W conversions were readily available. Not so much anymore. So in a nutshell you'll be spending a lot of money just to get "the look".

So, if you don't care about the UMP look, keep your USC
If you want the UMP look and don't want to spend a lot of money, get the HERA stock
If money is no object and you have to have the UMP look, do the conversion
Or, save your USC and go buy an already converted UMP. I've seen them as low as $2500 for a .45 conversion

Gotcha.. looks like I will be doing the full conversion due to the stupid and nonsensical 922r regulations.. (insert sad face here)

Here is the letter I got from LanWorld (nice guys to deal with by the way)

Steven,

The HERA conversion for the USC would actually be non 922r compliant so you would have to replace some other parts like the trigger pins, hand guards, magazines etc. So it gets a little complicated with the conversions but they are very cool. Let me know if you have any other questions, thanks.

I did send him a note if that was true even with the fixed rear stock.. will let you know what he says, but for now I'm considering it non 922r compliant.
