Building the Semi Automatic Uzi : Extra


Indoor Range

This is the 7th post of 7 posts about Building an Semi automatic UZI carbine.  See Posts 1 to 6 on thjis site buy choosing the category. Building the UZI from the category menu.

I took the UZI shooting again today, for it’s second time at the range.  It worked really fine again and I still pleased with the build.

Here’s a video of my associate firing it

Cool Case for the UZI


I have been carrying the UZI in a CMP case, above, I got from the Civilian Marksman Program for one of my M1 carbines.  But then I found this great violin case:


uzi case red


uzi case blue


uzi case empty

I found these violin case online from for $245.00 and I ordered one immediately.

I will update this post when I receive it.

Building the Semi Automatic Uzi : Part 3 of 6 : Painting

See Part1 and Part 2 Painting the Receivers In previous steps, I gave you the links on where to buy the fully welded and ready to go receiver and a completion kit that contained the parts you needed to build the Uzi.  In this part, I go into surface prep for the receiver and pistol grip.

The McKay Receiver came unfinished and looked like this:


receiver in natural steel

And the Pistol Grip lower receiver was used and looked beat up: before-paint


So I found some NITROCELLULOUSE GUN COATING: at D+D Sales for $14 a can. One can would do several complete uzis. Here are the specs:

  1. Bonds to aluminum or steel
  2. No baking required:
  3. Ready for assembly in 1 (one) hour.
  4. 1 hr – Very High Resistance to gasoline and oil.
  5. Paint Receiver, individual parts, and barrel. Thin coating allows painting inside the receiver and all other gun parts. Use single coat on internal parts or 2 light  coats to allow free operation of parts. Use multiple thin coats for best results, where binding of parts is not a concern.
  6. Post application temperature tolerance 250 degrees.
  7. For optimum bonding sand blast before painting or sand and clean with course steel wool and clean with lacquer thinner before painting.
  8. IF SAND BLASTING IS NOT POSSIBLE: CLEAN WITH course steel wool and Acid wash with DILUTE muratic acid (HCL hydrochloric acid), (Pool acid). Dilute to 1/5; (Some bubbling will occur; remove after 15 minutes.
  9. CAUTION:Do not breath fumes and use Rubber Gloves. Very hazardous if inhaled and it smells pretty bad.

Here is the receiver after several light coats. black Here is the pistol grip/lower receiver with the paint still wet. I had to take all the parts off  to paint it. wetpaint If your Uzi Cover is beat up, you probably want to take that apart and paint that as well. Magazine Catch, Semi Automatic Sear, Trigger and grip safety Assembly This diagram should help you assemble the rest of the internals and grip safety. stick Put the mag catch on first. The order you assemble the rest of the components have to be in this order, otherwise they don’t fit.

  1. Grip Safety, and spring. Attaches in the rear.
  2. Selector button and lever and spring. on the side of the stick
  3. Sear and pin. Inside the front of the receiver part.
  4. Trigger and pins. Near the front
  5. Grip and screws. On the outside of the stick.
  6. Now you have a completed lower receiver pistol stick.

The next chapter will cover assembly the upper Uzi receiver.

Building a Semi-Automatic Legal Uzi – Part 2 of 6 : Buying the Materials

The first step is to get all the parts for the build.

I should put a disclaimer here to look into the laws in the state where you live to see if you are allowed to have a semi automatic UZI.  Or what changes you might need to make it legal.
I live in a free state. I can have anything, including a real uzi if I fill out the Federal Class 3 paperwork, pay $200 and wait 8-9 months for the tax stamp to come back.  For a semi-automatic rifle in my state, I don’t even need a permit to buy one or build one.

I will including the parts in my build.  There are many sources for parts kits and barrels and magazines.  There’s only one source that I know of for the fully welded and ready to go, uzi receiver, and that’s McKay enterprises. You will need to have McKay send the Uzi receiver to a local FFL (Federal Firearms License) holder. You will do the federaal background check before they let you bring home the receiver.  To the ATF, the receiver is the gun.  All the other parts can be sent directly to your house.

McKay UZI type semi-auto bolt assembly. This receiver uses most of the Full auto parts like the stick grip, and top cover.

Add a barrel. I used a NH company. Green Mountain Barrels.

sear mag

Add a semi-auto sear to replace the one in the full auto kit ($27 or you can modify the full auto one) and a Uzi magazine from D and D sales.

Now that’s everything you need to build a semi-automatic uzi carbine. If you are using a full auto gripstick, you do have one two options Option 1: The ATF says you need needs a small piece of metal welded in the Full Auto Grip Stick, to prevent it from the selector switch from being put in full auto mode. Now. I understand your confusion. I am using the Semi Automatic Bolt, and Receiver, and a Semi Automatic barrell, and a semi automatic sear.  But since my Uzi Grip Stick is the full auto model, they still want you to permanently prevent the switch from moving to full auto.  You need to do this, or you may find yourself fined and jailed.  Or you can do Option 2: Buy a semi-automatic grip stick that has only two positions instead of three. See the photos below:

The next installment will cover paining the receiver and getting the parts ready for the build.
