UZI .22LR Conversion 40 Round Magazines

[delta-10]

This looks to be the best news in years for Uzi 22LR conversion kit owners. I ran across this over on Sturm posted by Subgun 24

"I finally have my UZI .22LR conversion magazines ready and for sale. $150 for 3 magazines plus shipping. If they don't work to your satisfaction, please return for refund."

Sturm thread: https://www.sturmgewehr.com/forums/...5-wts-uzi-22lr-conversion-40-round-magazines/

Check them out in this youtube video.

Outstanding. I will be ordering some soon.

Can’t wait to try these!

His mags are awesome too.

I have a brand new 22 kit that I have been putting off messing with, not anymore. My gun is a Fleming conversion with a semi trunnion and milled feed ramp. So I have to turn down the breech end and trunnion end to fit.
I also have a brand new 45 kit that needs the same thing done.

I just ordered the 3 pack. I can't wait to try them out.

Received mine today. Loaded one with 40 rounds and then noticed the instructions say they need a break in. It says to start with 10 and work up to more, so I unloaded and put 10 in each. One ran perfect, one had two light primer fails and then worked, the third had two failures to feed due to mag (empty chamber).

Then loaded 25 in each and two worked perfect and one had a couple light primer fails and then worked. Ran out of daylight to try more, but it seems like they are smoothing out. The feed lips feel rough when loading. Hopefully use will polish them. Will work on that tomorrow.

The plastic mag body is obviously 3D printed. Rubbing your hand on it or sliding into a pocket or pouch produces a sound like corduroy. The mag catch cutout is a little rough due to pieces of the 3D printing being left behind when it was machined out, but it worked fine. They are also a little snug in the mag well. They say that will also polish with use. So far, I am happy to have metal feed lips and 40 round capacity.

I don’t have an uzi 22 kit but I do have his 22 sub cal kit for the MK-760 (it’s awesome).
As for mags being tight, I think he makes them that way to help with variances / tolerances with different magwells.
When I first got my kit, the mags were kinda tight and I kept reinserting them. After a bit, they fit like a glove and are kinda formed to you mag well (I guess you could say they break in that way too).

Loaded 30 and then 40 rounds in them today and they all ran perfect! I will be buying more of these. They just need to break in.

Just bought 6 of these. Haven't tried them yet but they seem to fit well in my Vector SMG with Vector .22 kit. I'm optimistic.

I would like to know if there is any loading device for this type of magazine, to save a little time and skin compared to loading them round-by-round by hand.

Yeah, there is/was at least one type loading aid that Vector (and maybe others) used to sell for .22LR conversion mags. It's a standard 9mm/.45 ACP mag push loader with a grooved bar welded in the center of the pushed section. It's still push by hand, but it provides easier loading when the mag is almost full.

ETA: There also was a similar one made of plastic by Christie's. When Subgun Ord made and sold .22 Uzi conversions, the Christie's loader was included.

For pics of both types, see "The Uzi Examined" on page 292.

MHO, YMMV, etc.

I ordered 6 more and when they came this week there was a loader included! It is 3D printed like the magazines. I don't see it on their website yet.

 

[subgun24]

If any UZI talk members who previously ordered magazines would like a loader and/or a McFadden adapter. email me at subgunstore@gmail.com
I just need $10 for shipping and happy to send you the loader and adapter.

 

[Krink545]

I will get my order in soon. Can you post a picture of the McFadden adapter? I didn't know such an adapter existed.
Hope it also works for the BDM mags.

 

[Alaska_Shooter]

Is your McFadden loader adapter different than the McFadden Lage loader adapter that sort of sometimes works with Uzi mags? With how great your stuff looks I’m assuming that it is 😀

Will your Uzi adapter also work with metal conversion or Blackdog Uzi 22lr mags or does it only work with your Uzi 22lr mags.

Thanks!

I got 3 mags yesterday, they ran great! 40 Round Mags that run, that is almost unbelievable! I loaded a full 40, Ran 160 rounds of CCI mini mags W/O a single malfunction. I did controlled bursts & mag dumps. What is great about the mags is that I can use an unaltered lower. With the mags from Richard at BWE, I had to keep an extra lower with the mag catch altered to get the right mag height. 40 rounds, metal ejector these are a tremendous improvement over other mags! I could not figure out how to attach a one handed self filmed mag dump? But here are a couple of photos.

I just ordered 3 more, they are great!

Just ordered two packs! Love my 22 kit! Can you tell me if your M76 22 kit will work in my Stemple M76? It uses a M76 bolt from what I was told. It for sure uses SW M76 barrels as I have a GEMTECH SG9 suppressor for the SW M76 that works great on the weapon.

Took out the three new 40 round mags, total of six. Flawless Fun with CCI, the CCI standard were very quiet suppressed. I think that the Subgun Store achieved something that no one else has been able to do. They just empty so quickly. I may need to get a better loader and more mags.
