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.

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.

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