Uzi barrel services

[AKarms]

Just added a nice south bend lathe to the shop. Need to freshen up on it a little, been a few years since running one, but will be offering all uzi barrel modification services very soon.

How about making some of the barrels for the Swedish Training Ammo?

No idea what those are. Do you have prints or an example ?

Examples, yes.
It is essentially an Uzi barrel with a bore of .209 or .210.

The Swedish Training ammo looks just like a standard 115 grn RN FMJ.
But....
It has a 5mm steel BB in the nose.
The plastic around it disintegrates on firing. Only the BB goes down the barrel.

When this ammo was everywhere, there were a few folks who modified barrels with .22 liner inserts.
Problem is/was there was still some "slop" in the barrel as the BB diameter is 0.209 not .22

Had someone here make me a prototype barrel several years back.
I think, emphasis on think, that he took a standard Uzi barrel to the chamber and then threaded on a smooth bore .210 adaptation to make the overall barrel.

So I did some looking and can’t find any .210 barrel blanks. If it was as simple as forming 2 barrels into one I’d attempt it but I’m definitely not set up to make barrels like that. If you could find .210 blanks and had a donor barrel for a chamber I could make something work possibly. But seems like a lot of work and quite frankly something I’m not going to be diving into anytime soon. It’s just a cost vs time thing. If you could supply parts I could do the work at an hourly rate. But to just make the barrels doesn’t seem like there would be much demand, or much of a profit margin to make more than a few per order

The way the old barrels that worked and were safe were done was they were drilled and reamed to bore size out of tool steel. Contoured and hardened when finished.
There also needs to be a forcing cone effect between the chamber and the bore size to crush the Bakelite bullet.

I think I have a sten barrel around from that run way back when.

You Gentlemen are the subject matter experts... I recall the proper UZI spec. is 4150 and not 4140 steel. = IF this makes a "real" difference?
