IMI Mini Uzi Parts Kit 9mm review (with pics)

[darkest2000]

So the other day I was browsing on Numrich Gun Parts Corp looking for some SIG P226 parts, and noticed that they now have original IMI Mini Uzi parts kits available now, in my experience original Mini parts have been hard to find so I figured why not, for $323.95 (with dealer discount), it's worth a try. The kits come in two flavors: F/A (for $20 more) and SEMI, the kit shown here is a SEMI.

All the parts laid out:

The part that exhibits the most finish wear is the trigger group, although upon closer inspection, the metal is in very good condition and could easily be refinished to look like new. This is true for most of the parts found in this kit.

Front Trunnion Assembly with the correct Mini Uzi trunnion and type B sight:

Correct Mini Uzi top cover, not the chopped and welded type found on Vector guns.

Semi Bolt with recoil spring and striker assembly:

Rear Trunnion w/type B sight and Folding stock:

Most of the parts are covered in a black paint like finish which can be easily scratched with finger nail. I suspect it's just the original black finish that has turned soggy after being covered in oil for so long.

Anyhow I hope this is helpful for those that are also considering purchasing the Mini Uzi kits, it looks very buildable if someone would just make a correct, in spec Mini UZI receiver. It doesn't come with mags or barrels but those should be easy to source. These kits can't last long at these prices. Now if someone would just bring in the MICRO kits, life would be golden.

Must have went fast they are "This product is discontinued and no longer available"

That sucks you probably got the only one they had in semi LOL

 

[shadeone]

seriouly, there is no excuse for lack of receivers now. wtf.

funny that just recently the stocks alone were selling for half the price of these kits haha!

also, where are these kits coming from? the pic on numrich hows a full auto kit with a bolt with feet.

thanks for the review!

Yeah I just checkd the Semi kits are no longer available but the F/A kits are still in stock. I suspect someone (or company) may have purchased the whole lot from them, there are people selling the same Mini Uzi kits on GB and Sturm for $600~700! No clue where these kits came from though, South Africa?

Somebody please make a GOOD QUALITY receiver for the Mini UZI now that there seems to be kits available.

 

[root]

I was gonna buy one just to have.

Probably good they are gone, for me least, Last thing I need is another USPS flat rate box full of parts for a gun I don't have.

One correction.. Those aren't SEMI kits.. Notice the full lip and extractor on the bolt face .Trunnions are slotted for either bolt as well.

 

[darkest2000]

According to Numerich's description (before they took it down), these may contain parts that are converted from FA to Semi. The bolt does have a full supported bolt face but otherwise looks to have all the features of a semi bolt (using the UZItalk library as source), the trunnion is NOT slotted for a FA bolt.

Hopefully they'll be usable in my build.

 

[TitleIIArms]

Numrich is LOST.. LOL These are Original IMI SMG kits. Someone THOUGHT they were semi's because they have strikers like a semi. The trunnions,lowers,and BOLTS are all SMG. I spoke to them about it but the listing never got changed. U would need to weld up the trunnion feet holes for sure as thats a no no on a semi.

 

[darkest2000]

The trunnion does not have the bolt feet holes as far as I can see, at least we know it's from a closed bolt gun.

Anyone else want to chime in? Now i'm really curious.

 

[badboy0757]

Yeah, these are/were closed bolt full autos. But those are so rare to see for sale that even numrich didn't know what they were. I was gonna buy one. But wasn't sure about the legality of the full auto closed bolt. So I didn't get one. Apparently the BATF has changed their stance on a semi bolt with a full bolt face. The parts that I've seen have all been marked in english with the ARS lowers. So I don't think they came from south africa. My first thought was that these may be government agency demills. The ones that I've seen have been filthy and appear to have been sitting in oil for quite some time. Hopefully numrich can get more of them. Otherwise these will skyrocket in value.

Would love to see micro kits come around. Weird thing is some of these kits have the micro stock rather than the mini stock. I just grabbed a micro stock and receiver parts from one of these kits. I cut out the mounting plate and someday I'll use these to SBR my uzi pistol. Now if we could just get the correct sights?

By the way, receiver patches do come up once in awhile for these. These were made a couple years ago. There were less than a 100 sets made. If I get a good offer. I may sell them!

Sorry, these have been sold!

 

[darkest2000]

I'll bet that may very well be the reason why they're no longer available since Numrich finally realized their mistake. I was kinda worried that I'd get a micro stock in my kit because I wouldn't know where to find a correct replacement and I can't just keep buying those kits until I get the right stock LOL. But on the other hand micro stocks are so rare getting one would be awesome.

 

[TitleIIArms]

All the ones I've seen have the notches/small cuts in the bottom of the trunions, Open or Closed bolt. No reason for them to have to make two differerent styles back then. Maybe there WERE a few that didn't but I haven't seen it. Reguardless.... The FA Closed bolt has about a .075 smaller ID bore size from the frontend of the bolt down to the face . Try putting this bolt in your SEMI frame and it won't slide past the restrictor ring.

 

[badboy0757]

When I saw the stock for sale for such a low price. I couldn't pass it up. Came with the rear receiver section. After a bit of negotiating. I got the front and middle receiver sections as well. I carefully cut out the mounting plate so as to not damage the rear section. I really have no plans to build a mini. So, I'll probably just throw the front and rear sections in with the sideplates and put them on GB.

 

[darkest2000]

I can't really tell if the bolt has the restrictor ring clearance cut or not. Here's a pic of the trunnion though, for what it's worth.

 

[TitleIIArms]

Nope THAT one doesn't ..

 

[TitleIIArms]

Hard to tell on the bolt but if u set it next to a semi and look at the front end towards the bolt face u can see the slight difference. The SEMI ID is slightly bigger. You can measure it easy with a Dial caliber or just try to slide it into a semi frame. Also the inside taper cut torwards the ejection port has a wider cut line do to the bigger hole.

 

[darkest2000]

So if it has the wider ID does that mean I'm gtg to use this bolt as is?

 

[badboy0757]

Comparing your 8th pic to the bolt face from my pistols bolt. It doesn't look like its been clearanced for a restrictor ring. But it could just be the angle.

I don't have a caliper handy. But my machinest rule says its 13/16" at the bolt face and at the bolts front. Just a nudge under 2" from bolt front to restrictor ring clearance cut. Hope that helps.

 

[badboy0757]

Here's some pics from a build thread using those mini uzi sideplates. It was done with fullsize smg receiver stubs. But it would be way better with the stubs from one of these kits.

 

[badboy0757]

The rest of the pics won't upload for some reason. Been trying for better than half an hour to get up. I give up.
