I thought some of you would be interested in some of the things I do.  Several years back I got bored with buying guns so I started building them.

These two are some of the more recent projects I've worked on.  First one is a Finnish KP-31 and the second is well, obviously, an Uzi during the build stage.  Unfortunately I haven't had been able to finish up some other projects I have until I sell off some equipment of mine.

Also this is my first post.  I've lurked for a while but never created an account.  Finally decided to do that.

*Edit* I thought I had several pictures of the KP-31 on my Photobucket.  Turns out I don't.  I'll upload some tonight.

Here is the Uzi while I was working on it.

Here is how the Uzi came to me.

I am interested in seeing your projects in detail. Parts sources, build pics, that sort of thing.

Uzi looks fun.

The Uzi kit was from RTG Parts with a receiver from McKay Enterprises, semi auto bolt as well.  I have access to the equipment to do the semi auto bolt conversion but didn't have the time to do it myself so I just bought it.

A semi auto Uzi build is fairly easy if you buy the receiver and bolt pre-welded and converted, respectively. Past that it's just assembling some parts and doing some slight fitting and such.  For the Uzi you have to weld in a blocking plate so the selector can't go into the full auto position, and then remove some material from the sear feet so it can fit in the semi-auto receiver.  From there it's just assemble everything and paint/Cerakote/Durakote/Blue/Park/whatever finish you want.  If you don't get a pre-welded receiver you have to do some minor welding which isn't that hard.  Or if you really wanted to you could bend a flat and go from there.

The KP-31 was a complete fabrication though.  Reduced ID tube, redesigned FCG for semi-auto only, etc.  That project took several days to do out of frustration from trying to get everything fitting correctly.

I have a lot of interest in building an Uzi. Any other insight you can provide?

RTG Parts has an "Uzi Completion kit" that looks like the parts picture I posted, that's actually it in the picture.  Basically it doesn't include the bolt because you won't be needing it for modification and doesn't include the torch cut receiver sections either.  You have three options from there.  McKay Enterprises has receiver flats, bent flats, and bent and welded flats.  If you don't want to bend and weld, or don't have the tools to, buy the pre-welded and bent receiver.  If you can weld and want to to do that, then buy the bent receiver and the weld up kit.  It runs a little cheaper then buying all the required weld up pieces separately.  If you do want to bend, weld, and all that then you can go just the flat route (considered 80% for those interested).

Once you've finished all of that you have to install all of the other pieces like rear sight, front springs, etc.  Not hard, but there may be a little bit of fitting required on the top cover latch.  

Modifying the trigger group isn't hard either.  Once again it will involve some welding though.  You have to remove all of the parts and weld in a piece of plate steel.  All this does is keep the selector from going forward past semi.  That part is pretty easy, just mark where it stops on semi and weld the plate in from there to the front of the grip stick.  The last step is to modify the sear feet so they can fit in the receiver.  Dremel or mill just a little bit off and you're good.

That's about all I can give you as far as insight goes.  An Uzi build isn't a bad build to start if you've never done one before.

Feel free to ask any specific questions.

Damn.  I want an Uzi so bad.
