Freddy’s Note:
Here again, an answer to the question why do you need a gun at home. I really like the fact that he used a ak-47 to defend himself and shoot the bad guys.

Man Shot and Killed in Davie Home Invasion

Two home invasion suspects are on the run and a third was shot and killed by a Davie resident Thursday night, police said.

The incident happened at a home on the 6100 block of Southwest 48th Street, Davie Police spokesman Capt. Dale Engle said.

Three armed men entered the apartment and pistol-whipped the resident inside, police said. He then confronted the suspects.

“The resident of the apartment had possession of an AK-47 and after he received this beating he was able to get possession or control of that, and started shooting at these suspects as they were fleeing,” Engle said.

He received significant injuries but was later released from a hospital, Engle said.

The shooter was also taken in for questioning but has since been released. He is cooperating with detectives, Engle said.

Police have not released the identities of the four men involved, but said they knew each other.

Building the Semi-Automatic UZI -Part 6 of 6 Test firing the UZI


See parts 1-5 for instructions to source the parts and built your own Fully Legal semi-automatic UZI carbine I was delayed almost two weeks because of bad weather and a one week business trip, before I could take my new fun toy to the outdoor range and test it.


Above of pictures taken during the first firing of the finished Semi Automatic Uzi Carbine at the local gun range.

So my son and I took the completed UZI to the local gun range and we finally got to see if it would work. The UZI takes a little while to get used to, because of the grip safety.  This is the only gun I own that has a grip safety. So you have to push in the grip safety completely while you pull the trigger or nothing will happen.

I loaded the magazine, engaged the safety and the gun fired perfectly. This video below is a video of the actual first time, the gun has been fired.

There are 5 posts under the category Building the Uzi that explain where to get the receiver and parts and how to put them together. It has been a fun build and it did not take much skill other than to figure out how the parts went together.  I am completely happy with the build and I might even do it again and build a UZI pistol next time.

If you build yourself one from these directions, let me know if I missed anything.

Thanks and enjoy  Freddy

Building the Semi Automatic Uzi – Part 5 of 6 : Bolt and Final Assembly

See Parts 1 through 4 for the steps that need to be done, before you finish the build in this post.

Install the Folding Stock and Retaining Bolt.

The stock needs to be installed now before you install the bolt. Because the retaining bolt sits behind bolt and buffer block.


The round part of the retainer nut, hangs out the back of upper receiver.

Here is the stock I used. There several types of metal and wooden stocks available. You may have to use a wooden stock with this gun, depending on gun laws in your state.  In my state, I can use anything.e an


Look at the back of the Uzi upper receiver. This is a round hole.  You put the retainer inside the upper receiver and it will stick out a little bit. You now take the stock and align it with the back of the receiver and you can insert the bolt and screw through the hole at the back of the receiver into the retainer bolt.  You need to keep pressure on the retainer nut, while you screw in the bolt.


Once hand tightened, you need a allen/hex bit or driver to completely tighten the stock.  Once the bolt has been completely tightened, you can fold the stock under the receiver.

Assemble the Striker


The 3 holes in the different pieces must line up.

Take the black cylinder with a ridge on the end of it and insert it to the striker as shown above.  Not the holes in the black cylinder, the striker assembly and the firing pin itself. You must line up those holds and then inert the pin through all three items in order to hold it in place. Then insert the firing pin spring on the black cylinder.  The spring slides over the black cylinder.

Here is what the Striker looks like when it is finished.


assembled striker

Recoil Spring

The recoil spring is a large spring that will push the bolt back forward again to load another bullet and cock the action.

When you buy it separately or in a parts kit, it comes with a hard cardboard tab at the end of the spring. Very carefully cut the cardboard off without damaging the spring.

Here it is before


And after you cut off the orange brown tab.


Install Extractor into the bolt assembly

Here are the extractor and the pin that holds in in the bolt


extractor and pin


bolt and pin alignment

You can tell which end of bolt that the extractor is installed into but located the hole on the side of the bolt for extractor retaining pin. Then slide the bolt into the bolt assembly. Line up the notch in the extra to the hold and push the retaining pin in.

After the extractor is installed the inside of the bolt should look like this:


extractor position

Installing the Blocking Latch

The blocking latch prevents (or at least reduces) the possibility of having a round go off out of battery. If the round doesn’t chamber properly for any reason (bad ammo, dirty gun,…).  the a small spring and a small pin hold it in place. The spring and latch look like this:


latch and spring

It is inserted into the rear of the bolt assembly into a next to where the extractor was inserted.  Here is a diagram of the locations where the extractor and the blocking latch are inserted into the bolt.


Bolt assembly

Striker and Bolt

Put the striker spring on the opposite side of the firing pin on the black clyinder. Then insert the  large recoil spring in the round hold in the rear center of the bolt.  It will look like this:


striker into bolt

Twist the striker assembly so the black lever fits into the groove on the right side of the bolt.

Here is a closeup of the two components fitting together.


closeup striker into bolt

Take the black buffer block and position it so the recoil spring goes in the hold at the top and the striker spring does into the larger hole at the bottom.


completely assembled bolt, striker, and buffer

Be careful with the whole assembly, it is not fixed together. The components will fall apart if you are not careful.

Now you take the whole assembly and insert it ,buffer block first into the back of the receiver.  You will have to compress the spring by compressing the bolt towards the buffer block.  The buffer block will slip mostly out of site under the top cover catch and rear site assembly.  It will look like this.


bolt in gun

Once the buffer block is in place under the rear site/top latch, keep compressing the spring until the whole block fits into the receiver.

Now you can put the top cover on.  You will have to push the top cover latch back to put the top cover on. Then release it and it should spring forward and hold the top cover on.

Joining the top Receiver and the Bottom receiver

The bottom of the top receiver has a hole with a tab on the front of the bottom receiver will fit into.  Here’s the bottom of the receiver. I have circled in red the areas where the bottom receiver/pistol stick will attach to:


where lower attaches

So take the bottom  receiver/pistol grip stick and a angle and try to get the tab to fut into the opening (red circled).


lower into upper

Once you have the bottom part inserted into the tab of the upperpart, then push the bottom towards the upper until it touches.

Then a pin mm is inserted through one side of upper, through the lower and out of the other side of the upper. Use a rubber hammer to push the pin through The hole win the pin is inserted is circled in red in the picture below.


Here’s the pin


Try to Dry Fire it

Once the pin is installed, you are done, the built is complete. You can now test to see if the components are properly installed by pulling back on the cocking handle on the top cover, then releasing it.

Now try to dry fire it by simultaneously holding the grip safety and pulling the trigger.  If it goes click, then you are mostly likely ready to test it with blanks or real bullets.  If it does not dry fire, you may have to take the upper and lowers apart and the top cover off to inspect the fit of the parts, or to see if there is something impeding the bolt or the trigger.

Here is my finished semi-automatic UZI Carbine. In my final post, I am taking the gun to the range and will have pictures and video of the first time we shoot it.


UZI Build Complete

Building semi automatic Uzi – Part 4 of 6: Assembling the new receiver

Both Sites, top catch, and barrel catch

Both Sites, top catch, and barrel catch instructions

In the first three posts, we took a brand new semi automatic Uzi receiver and some Uzi parts from a parts kit and painted some of the parts. We also changed out the fully automatic sear for a semi automatic one, and we had a piece of mental welded into the Pistol stick grip to satisfy the ATF rules on converting a fully auto pistol grip/receiver to a semi auto one.

Putting together the Rear Site/Top cover

Before you can install the rear site, you must put the top cover latch and spring in place in the rear part of the Uzi receiver. They go right under where the rear site will be assembled.

These are the parts.  Nut for the real site screw is not shown.

Top cover catch and spring

Parts that make up the top cover latch and rear site.

The latch I got in the parts kit and the spring are shown in the picture below.  They were a little beat up, and I ended up replacing them with new parts.  Also, the surface of the receiver got scratched up when I had to bend the tabs that hold the top catch in place.  Since this area is covered when everything is installed, I didn’t feel I needed to touch it up.

Top cover catch and spring

Top cover catch and spring

Do not push the latch in all the way yet, there is a metal piece that goes over the spring and the latch and snaps on to the ends of the metal tabs.  It keeps the spring and latch under press and keeps it from shooting out from the end of the gun. This is what it looks like:

This part holds the top cover latch and spring to the receiver and acts as a base for the rear site

The front is at the right. The rear as at the left. Push the catch and the spring in and this snaps over both of them on to the tabs on the receiver.  The little rising area in the top of it is used to give the rear site some pressure and hold it in either of two positions.

Once this piece is in, you can put the rear site into place. There is two holes on the sides of the area where the site goes.  The screw goes through one side, and through the rear site and out the other side. A special nut is then put on the bolt to hold it in place.

The parts that make up the front site

This is three pieces. A washer, the front site , and the front site nut.

This is a hole at the top front of the receiver.Put washers, then nut, then screw in the front site. You can use your fingers to twist it in, or you can buy a uzi front site adjusting tool for fine tuning the site after the gun build is finished.

Barrel and Barrel Catch

If you look at the front of the receiver. Look to the left where the barrel goes. This is a small opening in the receiver, right above the  barrel.  This will hold a Spring and the Barrel Catch.  This device holds the barrel in place.  When installed press the Barrel Catch and then you can unscrew the barrel nut

Barrel Catch and Spring

Installing the Barrel and Nut


Since this is a semi auto receiver, you can only use semi auto barrels. This receiver has been designed that full auto barrels do not fit. This a a half moon ridge on the top of barrel and there is a similar half moon ridge on the receiver. When place together it fits perfectly. Full auto barrel would not fit.  Once you have the half moons put in the correct positions the barrel snaps into the trunnion with a perfect fit.  You then screw on the barrel nut.  When the barrel nut is almost in place, you may have to press the barrel catch down for the last few turns. When you release the barrel catch, it firmly holds the barrel nut in place.  To remove barrel, you will have to hold the barrel catch down for the first few turns as well

Top Cover alternation to Full Auto Cover

If you are using a semi auto Uzi top cover, then you need to make no alternations.
But if you are using a cover from a full auto Uzi parts kit, then you need to make one change to make it legal.

How can you tell which Uzi top oover that you own. It’s very easy. Pull the cocking handle on the top. Then let go. It should  slide back when you release it.  That’s semi auto.
Do you hear a ratcheting noise and when you stop pulling the cocking, level does it stop without going all the way back, well then you got the full auto top cover.

Some people suggest taking the cocking knob and corresponding assembly on the other side apart. I have a much easier way.

This is what the cocking lug looks like when it take it apart from the top cover (Don’t do it)

Screen Shot 2013-12-08 at 6.59.30 PM

Under normal conditions you could just unscrew the screw in the cocking knob that goes though the top cover and attaches to this cocking lug.  Unfortunately, most of these screws have been staked. They will not easily come out without drilling or ruining the screw.

Look closely at this assembly. There is a wire tab sticking out the front of the assembly. Just take some pliers grab it and pull it off. This is what it looks like:

Screen Shot 2013-12-08 at 6.59.03 PM

Once this wire has been removed, the cocking level should pull back without any pressure, when you release it, it should slide all the way forward.

Here’s a diagram with an arrow pointing to the wire that should be removed.


Top cCover Wire Removal

You are finished with the Uzi top cover modification and the exterior parts on the Uzi Receive.

In the next and final post, we will assemble and install the bolt and finish the build.  I also have pictures and video from the range, where we fired it for the first time.
