UMP Conversion

[sniper dude]

I thought It would be sweat to get a airsoft UMP since no one else would have it but it would all have to be custom work. I think I would get a MP5 RAS and then throw a G36 stock on and some how get a uzi mag to fit. Any help would be welcomed.

[sniper dude]

Hers a link to a pic of one for those of you who don't know what one looks like.

Heres a pic of an airsoft UMP, it looks pretty sweet but I have no idea how someone could make it. http://www.airsoftcommunity.co.uk/gallery2/albums/userpics/10263/custom%20%20ump%204.jpg

I believe that the UMP is comprised of mostly MP5 and G36 parts or parts that are similar to the two weapons, so i guess getting both of those would be a start. I also think a UMP would be a nice thing to have in an inventory.

If you don't like reading threads like that, don't read them. If everything had been covered before, there wouldn't be much reason for forums, would there be? I'm sure there are many threads on the UMP before this one, but this is a new one.

I've always had a hard time swallowing the UMP's form factor. Most of my concerns about the gun are more towards its real-steel version (the sluggish recoil of a .45 cartridge with no recoil spring in the stock... awkward).

[Hudak]

Yea, the real-steel version seemed extremely weak. I've been to plenty of gun shows and they just don't seem like a powerful gun. All my friends love them but I'm more for the M4's.

Thank you, MB38x its about time :D

As far as the mag solution for that gun, all you would need to get are some mp5 straight mags for it.

[MB38x]

Who sells 10mm/straight mags for the MP5?

[Code3 From Co.C]

I second that question. I can't find those things anywhere. They are as elusive as an RPK motor drum mag.

P.S.-- I've done my research on the RPK mag. In one of the earlier discussions Fox said they had to be custom made. So I'm not trying to start a tangent topic, I'm just trying to reflect on how difficult the MP5 strait mags are to find.

[Kendodude]

You know for a minute there, I thought that was made by Gunkulture.com since they hella make custom guns (HK21... DROOL... screw RPK). Because of the tiles ya know.

Who makes those? Airsoft surgeon? some dude no one has ever heard of? eh? eh? My friend would really get into airsoft if there were an UMP.

[Code3 From Co.C]

Well,.... Gun Kulture is about 10 minutes away from my house and I can say that they are a couple of great guys who could make you an airsoft bannana if you were willing to fork over the cash. I'm sure they could make a UMP-45 if you had the money. Note how I focus on the $$$$$$. Their custom jobs are ultra high quality and their prices reflect that.

[Jedigreedo]

Ya know in Airsplat ads I've seen them picture an MP5 with a magazine that's straight and at an angle such as the UMP's. You might email them and ask them about it.. Considering what they deal in though it was probably some odd springer thing or a custom pic.

[Cobalt-Blue]

the UMP is a g36 stock/reciever modeled for the .45 ACP cartridge

also don't forget about the Thompson strait mag! it just may be a better representation of .45 mag.

I've discussed making one with a local airsoft retailer who does custom works and the biggest issue in converting a G36c is changing to a smaller magwell. one could make a g36c into a UMP with some modification and the scale would not be far off, but it would still be too large to be 100% correct.

also the 55 grain ss109 5.56mm nato bullet fired by the m4/m-16/steyr/g36/la85 etc nato assault rifle does not have in close ranges, the sheer brute force of the .45acp. what it does have is superior trajectory and the capability to pierce armor and remain accurate far longer than the .45acp- since it is a rifle round and not a pistol round. there is no fair comparison between them. the UMP would never replace an assualt rifle, it's a subgun.

the .45acp= close quarters manstopper
5.56nato= light assault rifle cartridge

upon re-inspection of the above photo you can see the G36c magwell. that looks like a chopped g36c without the top rail and with some form of strait mag

[almega]

just as there are chop jobs in airsoft there are chop jobs done in the real steel world (carbine pistols, 9mm / .22 mods for ar15 series, etc);) especially w/ the g36, you can do all kinds of stuff and make all kinds of variations for it. Pretty sure you'd need a kit to change the chambering though

[ArmyHummer]

The 10mm mags for the mp5 aren't in production yet. There is a rumor that some company was going to make them, they even proposed it, but no one really found out much past that point. That mag is probably just homemade or something. But as far as mp5 straight mags - the 10mm ones, there are none currently in production at the time. I have seen af ew custom ones made from real steels though, they looks alright, but had too much chopping and dremeling done to fit into the gun.

Btw, there is also a guy on arniesairsoft.co.uk that has made two UMP's so far, and he sold the first one, expecting to sell the second here soon. You should probably go check it out as you could buy if you have the money.

[Lu]

I remember seeing a post (maybe on Arnies) of people group ordering straight mags from a custom place. They do exsist, just not sure who that custom place is.

[Legend]

Side question.... why are there 9mm rounds next to that UMP? :confused:

[ArmyHummer]

They werent to ORDER custom mp5/10 mags, but to vote on how many people wanted them. To try and make the company make them. Like I said, they are either still in the process, or not really concerned with it now and dont see a market in them.
As for the 9mm rounds next to a 45 cal UMP, same reason why in my gallery pics of my guns I have 223's around my mp5's - probably didnt want to go out and just pay 10 dollars to keep someone from asking the question, why are there 9mm rounds next to a 45cal gun? :D

[Code3 From Co.C]

Well since we're nit picking:

- Why after all the modifications necessary to make a UMP-45 did the maker not just use the selector switch from a G-36 instead of an MP-5.

- Speaking of which... That isn't a modified G-36. If you look closely at the contour of the pistol grip, you will see that it is a modified Navy style MP-5 receiver.

- Why does the barrel to this supposedly .45 cal gun look like it shoots .22 LR. Heck, the barrel isn't even thick enough to shoot the 9mm rounds on the ground next to it.

- I don't think it is an M1A1 mag. Thompson mags have a "rib" on the back that guides it in to the receiver. It is most likely an Uzi mag.

Well since its an airsoft gun it doesnt needs to shoot 9mm, .22 or .45 ammo, it only need to be 6mm wide to shoot small plastic bbs :rolleyes:

and i must say if that thing is fully functioning its the sweetest damn custom airsoft gun, i have ever seen, nitpicks aside.

[ArmyHummer]

We sholdnt have to scrutinize that bad lol
And hint: obviously he didnt have a G-36 for G-36 parts ;)

[necronomicon]

Magazines should not be a problem. If you search for pics of the UMP, you will find that there are also curved "MP5 Style" mags it can take.

I am willing to predict that due to the growing popularity of the gun, a conversion kit could easily be made for the G36, since the back end of the gun is nearly identical. I would like to see one be produced by TM, but thats a long shot, considering they are busy with the M14. Keep hoping for it, because I sure am. It just might be a while.

[Lu]

I agree, I'd love to see a TM UMP .45, also like to see them make the H and K XM4 once it is finished and regulary used (which i bet it will be in the future.)

[sniper dude]

I know they make UMP with curved mags but my opinion they look just plain ugly

[random_irish_hero]

'tis a beauty that one....an airsoft wet dream:D
