Two of my micro UZI pistol with different conversions. Could use some of your wisdom.

The first one on the left was converted using a method that mimics the operation of a factory Micro. Builders used a factory pistol closed bolt on which they restored the lower lip of the bolt face to mimic a factory fully supported bolt face like that of a full auto Micro closed bolt, along with additional trigger housing mods as well. The one on the right used a method that was put into print in the form of a booklet called “Micro Uzi Machine Pistol semi auto modification manual” by Firepower Publications in the mid 80’s. It’s still available today in reprint from Delta Press online. This method was the least desirable way of converting the pistol as it required the fabrication of a complicated trip device, mods to the bolt, receiver, trigger housing, and elimination of the grip safety. Both are nice examples of the history of the methods used to convert these weapons to select fire back in the day.

Wow, I've never seen someone with that conversion. I had a RR Micro that was cut for the conversion. I also had the modified striker arm with welded on catch for the secondary sear. I always kept an eye out for those conversion parts as I thought while more complicated, it was a more 'proper' way to do a closed bolt full auto for the UZI. I remember seeing the parts one time in a zip lock bag at the SAR show someone had at a table and offered to buy them but the guy said it belonged to his brother and they weren't for sale. I was always tempted to make the parts but also involves making a flat spring and I didn't want to deal with trying to make the spring too.
I thought if everything worked it would be more reliable and a slightly lower cyclic rate but again I've never seen one. Is yours reliable and have you clocked the cyclic rate of both?

I’ve never shot a gun #2. It cycles fine by hand. I am not crazy about it have a hole where the grip safety used to be.

Gun #1 guns crazy fast like you’d expect.

I am looking into full micro conviction on both to make them more functional

Give John Andrewski a call well worth the services. Tell him Joe from Subgun Ordnance recommended him. PM me if you are in need of his contact info.

I do full micro conversions. I manufacture the stock hinges, bayonet lugs, sling swivels, I have reproduction stocks coming in a week or 2. I install and refinish

We are working on one now. Remarked lower “A. R. S.” Remarked to “Micro Uzi” and some other mods. Not the traditional bayo lug up front but a small piece of picattiny rail. Newly gloss black Cerakote and some color fill. Also Instead of searching for a traditional Micro Uzi stock folder. We used Sams at Practical solutions variant. I like it better. It’s heavier and locks in better. YMMV. This project is definitely a labor of love. Also thanks to member amphibian for the idea of the stock “Wrap” material. I love it. Very nice idea.
