Hello and welcom to the non-lurking part of the forum :-)

Marushin UZI is a fantastic modelgun, even if often they are beaten up and do not look that good. Browsing through forum you will find that many folks here have restored their UZIs to great shape using various methods.
John is a great come-to chap for modelguns :-)

Have fun!

Try to post some pictures of the bolt. Close ups of the underside and the bolt face would be good, your right its a very early one, these used a single not double stack magazine, is the mag that it came with single stack? a pic of the top of the mag will help.
It used an old open cart (an open cart that is just a case with a cap at the bottom, not the modern piston multi part carts)
Those carts are REALLY hard to find!!!
Now the problem is the det pin in the barrel, the new type carts need a thinner pin, the one in there is to FAT.
PROBLEM I have seen a lot of these and never been able to get the pin out! I have spoken to others who have had one and got the pin out, so does you pin unscrew?? I thought mine were just siezed, but they were not they were fixed.

So bolt pics, and see if the pin comes out, and mag pics Smile

not a whole lot of progress on this had a good look at the newer version bolt and it doesent look like it whould be compatable without a few mods
det pin wise still wont budge ether

the barrell doesent look like it will be much of a drama to make a replacement on a lathe with a removeable det pin for newer carts, just need to see if anyone i kow has a lathe i can use for a few hours

i do have a second newer version of the uzi that i picked up recently as part of a batch of filmprops in with a few airsoft bits blank firers and denix stuff allong with a load of the older 5.56 carts and about 30 boxes of caps Smile (that was a nice surprise)
anyone know of were i can get a new det pin for the newer uzi as its missing?

Hi akazz

I've tried disposable carts (WaShan 9mm) in a few of my models. They're best suited to pistols that'll accept them in my experience. I tried them in SMG models, MGC MP40, Stirling, Sten e.g. but found that heavier bolts either broke the cartridge, or that the cart didn't have enough power to blow back the bolt.

The best cartridges to use in Marushin UZIs are either MGC P220 with a suitable Det.Pin. For safety's sake please DO NOT attempt to use BlankFire rds as catastrophic damage will occur.

Hi akazz

The problem with using blanks has more to do with the Marushin UZI being too weak to withstand the pressures generated by blanks rather than UK Gun Laws. Many a PFC modelgun has been blown to bits by people thinking or being misled into thinking they'll take a Blank.

Some of the earlier steel models are convertable but even they need extensive strengthening.

The P220 cartridge works particularly well in Marushin UZIs anyhow so stick with them to be safe. Even though MGC stopped making them, I know John at PFCGUK has a good stock of them so get yourself a few boxes now Wink

Just to add my 0.02 cents regarding blank ammunition: Standard off-the-shelf 9mm blanks, whether crimped or PAK, bought from gunshops would be too powerful. However, if you downscale the power of the blank, then you do increase your chances of having more success in making it a true blank firer. Especially if the modelgun is steel construction. A lot of production companies use that method - 3/4 load, 1/2 load, 1/4 load, 1/8 load ect. There's a company called Kynoch that will make up blank ammunition to customer spec, so if you want, for example, 500 9mm crimped blanks with a 1/4 load, they'll do it.....for a price obviously.

You may recall one of my first forum posts was about my successful conversion of a model gun M4 to true blank fire. That was possible with M200 crimped blanks (not Kynoch) made to order with I think 1/16 load.
