I think the first Group Industries receiver built into an SMG by Vector is S/N 100082 or something like that.

As a data point, my GI built Uzi is serial #10033x and was purchased NIB long before Vector bought those receivers at auction.

Good choice on selecting an UZI!
If forced to pick only one SMG currently available to regular citizens, it would be the UZI due to it's versatility and iconic status as well as shooting comfort. These days, with all the aftermarket conversions available, most first time MG buyers choose a MAC. But to me, MACs are ghetto and all those conversions make the gun look hokey. I guess if your goal is to just send FA rounds down range in as many different calibers as possible on a budget, then it fits the bill. But growing up in the time of action movies, the UZI was the star of the show in a lot of them and it feels good to channel my inner action hero every time I shoot the same weapons my childhood heroes did.
You're never going to get that kind of satisfaction when shooting a MAC with a conversion.

As far as .22 conversions go, I actually prefer shooting .22 in my UZI rather than 9mm. And if you follow Richards step by step tutorial for tuning a .22 kit, you can get it to work very well. I just wish someone would make a nice, laser cut professional shim set for the extractor. I used an aluminum can and cut shims with shears, which is really ghetto but works.

Seems .22 kit problems get discussed more than trunion weld failures. Maybe reporting bias, but don't know.

My Vector kit runs like a train in either receiver, so long as I use minimag/blazer power level ammo. Bought some extractors from Tom Bowers, but have yet to replace the original.

Hard to imagine a better way to introduce someone (especially kids) to full auto. Our kids used to shoot up pumpkins in the fall, and snowmen later on.

Every once in awhile drop the lower receiver and clean out all the unburned powder and wax, tho. Same for the mags. .22 is dirty.

I got mine to run well, so now I'm going to try and slow the RPM down to make the fun between reloading mags last longer.
I was planning on sending the bolt to Richard but after his diagnosis, I thought it prudent to wait awhile. If I had been more impatient, my bolt would most likely have been lost in limbo, never to be seen again (at least not be me).
But to slow the RPMs down, it looks like a part of the aluminum bolt is machined away and a tungsten steel weight, machined to the same size as the aluminum removed, is secured in the area where aluminum was removed.
I suspect the added bolt mass is what slows the RPMs.
If that's all there is to it, I know someone with a mill.

BTW, my father is originally from Dover-Foxcroft. Still has family in the area, if I'm not mistaken.

FYI, neither Group Industries nor Vector built the guns in strict serial number order.

I used a 9mm buffer/spring till one of the Uzitalk sages told me the .22rf spring is weaker, which slows ROF. It does go through mags fast, but haven't wanted to mess with the bolt.

Interesting about your dad, we've lived here since '92. One perk: we shoot Uzis right behind the house.

I tried literally everything

Another Vector here. Runs absolutely non-stop.

It had bad ejection when I first purchased it. Upon cleaning, I discovered that the prior owner never removed the grit and grime from the extractor channel. It was a solid cylindrical column of carbon. Cleaning that fixed it right up.

I wish you were here in Missouri. You could come over and after a couple beers and an hour in the shop we could get that thing running right.

OP you chose right. Whether it's a Group or a Vector, you are assured that it was a full auto from the start. My Vector has never skipped a beat in 9mm or 45. After I tuned it using the instructions here, I would put my 22 kit against any other in terms of reliability.

Congrats on buying one of the most iconic submachine guns ever made.

I have owned both. The IMI RR is the one to get. Rover Dave the moderator says the same. "ALL" the GI receivers are out of spec. Yes, Vector did a good job of straightening things out but not 100%. The IMI receivers are GTG.
