Marushin UZI... Basic Strip Down Guide

Basic Strip Down... Marushin UZI

***UNDER CONSTRUCTION...UPDATED PHOTOS TO FOLLOW***



When I bought my first model gun I had no idea how to strip it down for cleaning and inspection. On-line help from forum members here got me sorted so I thought it might be a good idea to post up a Step by Step guide for Beginners.

The Marushin UZI is relatively easy strip, dismantle and maintain. Just like its real life counterpart, it was designed to be a solid and reliable weapon capable of being taken apart and maintained by a soldier in the field with the minimum of tools.

Cleaning, Inspection of components and Re-assembly will be covered in separate Step by Step Guides so this guide begins with your UZI in need of dismantling after firing.

Step 1. Magazine Removal

Push the magazine catch, withdraw the magazine...

Step 2. Remove Top Plate

First make sure the Bolt is fully forward.



Push this spring loaded catch back



...and lift the top plate up



Step 3. Removing the Bolt Carrier, Recoil Spring & Guide Rod

Pull the Bolt Carrier back against the Recoil Spring's pressure and lift the assembly up and out of the Receiver.

Be Warned that the Recoil Spring is strong and as the UZI is an all metal model there is every chance you''ll get your fingers pinched if the Bolt snaps forwards (I speak from experience... it hurts too!)



The Bolt, Recoil Spring & Guide...



Step 4. Removing Bolt from Carrier



This socket head screw locks the Bolt to the carrier



Simply unscrew this, push the bolt to unhook it's "clip" and pull it free



Step 5. Removing Detonator Chamber Assembly


Removing the top plate by unscrewing these 2 cross head screws detaches the chamber from the Receiver



Pull the Chamber assembly away from the Lower Receiver

Step 6. Removing Detonator Pin

Unscrew this cross head screw,




...push the Detonator Pin out and clear. The Pin can get very dirty and clogged up with deposits. It can stick inside the chamber and may need some persuasion to remove.



Step 7. Removing Trigger and Mag Well Assembly

Remove this Screw...



Push out the Retaining Pin



Push the Grip Safety switch inwards, and tilt the Grip assembly up and away from the rear of the receiver



The Grip Assembly has a locating peg that slots into the Receiver, don't force the assembly clear as this could snap off



Step 8. Removing the Barrel

Grasp the Barrel Retaining Ring, push inwards, towards the receiver, then unscrew until the barrel and ring pull clear.

Your UZI is now stripped ready for cleaning, inspection and re-assembly...

Cerwyn

Do you still have these guides pal

Hi Cerwyn

Thanks for your reply, much appreciated.

I've sent all 3 back to the seller, he's going to have a look at the Uzi, and I've asked if he could keep the 2 Berettas and order me the correct parts.

I meant to ask, the firing pins in the Berettas, should they be metal or plastic, as I always though they would have bee metal.

I've got a good collection of deactivated guns (1 old spec uzi which cocks and fires, 1 new spec Uzi, sawn off shotgun, a Beretta centurian 92 and my pride and joy, an old spec Franchi Spas 12 :-D I'm missing the hook.

I really want to get involved in the model guns as I love the whole concept, and from what I've experienced on here, your all so friendly and that's what I love

Thanks again pal

Hi Cerwyn

The company got back to me and they have been brilliant and found the problem, the original firing detonator was bent slightly, they have fitted a new one and have test fired and it's firing as it should, so very happy on that front, they will also order me the parts needed for the 2 Berettas, so can't wait to get everything all sorted :-)

Thanks for your reply pal, I honestly didn't know about the metal firing pin being illegal, I naturally thought it would have been metal so it pushed the catridges harder (feel stupid)

Hi Cerwyn

The company is called (mg props) they have been good this last bit, they said to send the uzi back and they would check it over, they found that the original detonator pin that screws in was bent, that's why the rounds would jam and not cycle properly, they have fitted a new pin and looks level and spot on, they said if it was a problem caused by me, is need to pay for return postage, but if the problem lay with them, they would send it back postage paid.

It's good that this forum and the members are friendly, regarding the airsoft forums, I've seen many members being laughed at for their basic knowledge.

I fully understand regarding the use of steel parts, it's like with my deactivated guns, if I was to modify (which is impossible with new spec ones) then it would be classed as a section 5, just like airsoft guns that fire over certain joules.

I'm looking to get a Mac 11 to go with my uzi :-)

I meant to ask, I bought prop powder and have no idea how to use it or what it's use actually is.

Any help is appreciated pal

Thanks again Cerwyn

Thank you pal

I appreciate the help.

When I bought the prop powder, i didnt get any instructions on how to use it, but I`m presuming that people who buy prop powder, should know how it works before buying.

still trying to get my head around everything

Thanks again pal
