Uzi Part 3 of 7: Preparing and Permanently Attaching the Wood Stock

1 Comment

Uziel Gal considered a number of different stock designs until they settled on the final design in December 1950 and did the first production run in 1951.  The wood stock evolved as they corrected breakage issues and you will see stocks with different profiles over the years.  Purely FYI, The steel folding stock was added in 1956 due to Israeli paratroopers requesting a shorter weapon.

Legal Disclaimer – I tried to sort through how to permanently attach the wood stock to avoid creating a SBR.  There aren’t any ATF letters specific to this method. My approach is based on a method documented on Uzi Talk and that approach has not been legally questioned since the forum posted it – click here to read their guidance.  You will need to decide if this approach is acceptable to you.  I am not a firearms attorney nor do I claim any regulatory expertise and you accept all responsibilities and liabilities for compliance with all federal and local laws that pertain to you.

The problem is that if you remove a quick detach stock from an Uzi with a 16″ barrel, then it falls under 26″ then it is a short barreled rifle (SBR).  Thus, the Uzi’s wood stock must be permanently attached.  Let me point out there is a ton of fear, uncertainty and doubt (FUD) in terms of the converting the quick detach wood stock to be considered permanently attached.  The consensus of cooler heads seems to be that if you attach the stock to the Uzi such that it can only be removed with tools, then it is considered permanently attached by the ATF.  If you think about it, most shotguns and rifles would be too short if their stocks were removed for maintenance and they all require tools to have their stocks removed and, thus, are no longer “quick”.  The Uzi wood stock bracket is modified by having the rear receiver attachment point ground down and connected via a blind screw that can’t be accessed without first removing three external screws and pulling the wood stock off.  Most of my long arms have the stock secured by one screw that may or may not be exposed.  For example, a shotgun’s stock screw is typically located under the recoil pad.  Many rifles have one or two exposed screws under the action.  In short, the Uzi’s stock is now permanently attached following the same logic.  This is a well trod path as many individuals have posted write ups and videos about the conversion plus JJ Custom actually sells brackets that have already been converted.

Preparing the wood stock for the Uzi may take you a bit depending on repairs and the finish you choose to use.  I looked at the stocks in both of my Uzi kits and the first one was in the best shape so that is the one I used.

There are a number of things that must be done at this point.  To reach the minimum 26″ overall length requirement, the stock must be permanently attached so I’ll talk about what I did for that plus the stock needed to be stripped, the gouges fixed and the wood refinished.

In my first kit, the screws were all in very good shape.  In the second kit they were chewed up.  I can’t stress this enough – use bits that fit the entire screw – this means both the length and width of the blade edge.  By full supporting the slot, you can turn quite a bit.  If you have an ill-fitting bit then you will tear up the metal.  Here is the Weaver set that I use all the time – I may use the included screwdriver handle or put the bit in my Dewalt screwdriver to save my wrist – it just depends on what I am doing:

This is the 88-piece Weaver Deluxe Gunsmith Kit.

1] Remove the screws that attach the stock mounting bracket to the stock.  You can see the big one at the rear and then the two screws towards the front.  I used a big bit to get each screw moving – that is why they came out without damage.  By the way, you can see how the old quick detach method worked – the front of the bracket slid into the grip lug, the pressure plate between the screws supplied tension with the rear cylindrical receiver attachment point slid into the receiver.  The lower catch just locked the assembly in place.  It was an elegant design really but one we need to eliminate.

Here’s what the bracket looks like.  By the way, you can see one of the big blade bits in my DeWalt power screwdriver.  The quick release lever engages or releases the notch in the receiver and the cylinder pushes into the receiver to lock it in place.  We’ll come back to the in a minute.

2] The next step is to strip the wood.  Use your favorite wood stripper, such as BIX, or brake cleaner to get rid of the tons of oil that is in the wood.  I used a ton of brake cleaner as it was snowing outside and I just wanted to get it done 🙂  If it were warm weather, I would have used Bix 2-3 times to get all the crud out.

3] I then mixed up a batch of Brownells Acra-Glas liquid epoxy, added black dye and glass fibers and then filled in all the gouges.  The epoxy then sat overnight and cured.  In cold weather, make sure you do something to keep the epoxy warm so it will cure properly.  (Click here if you want tips on how to work with epoxy).  Also, I added links to it at the end of this post.

Note, you can barely see two hairline cracks in the front of the stock to the left and right of the bracket.  They were repaired with quality thin viscosity super glue — I like the Bob Smith brand personally and use his different formulations all the time.  This stuff is very thin and readily runs into cracks.  I just push the crack open, pour in the glue and then clamp the work for a minute while it cures.

4] I then sanded the stock down starting with 100, 150, 220 and finally 400 grit sandpaper to get it smooth.  I purposefully used black so they would look like repairs or burns.  I figured this Uzi was older than me and ought to have some character marks to remind people of its age.

5]  I rather liked the color of the wood in the parts kit so I used a 50/50 combination of boiled linseed oil (BLO) and black pine tar.  Now this old school blend actually protects the wood and gives it a really nice slightly darker matte finish bringing out the color of the wood.  So you can see we went from a yellowish color above to warmer orange-ish brown below.  You apply the finish using a foam brush and chase it into the wood using a heat gun.  Literally this stuff should be bubbling from the heat.  You then wipe it down with a clean rag and repeat until you get the finish you want.  I then go over with 0000 steel wool to make sure it is nice and smooth.

Note, properly dispose of BLO soaked rags as they may spontaneously combust from the heat of drying.  The proper method is to lay them flat on a noncombustive surface and let them dry thoroughly.  The length of time depends on many factors.  I burn mine.  Never ever just throw them in the trash.

6]  Next up we need to convert the stock bracket to be permanently attached – meaning it must screw into the receiver.  I have seen several methods used and I’ll share with you what I did and you can decide how you wish to proceed.  If you are uncomfortable with the machining required, a firm known as “JJ Custom” sells the brackets already converted.

6.1]  This is what the quick detach stock bracket looks like in the first picture and the cylindrical protrusion normally slides into the circular hole in the end of the receiver shown in the second photo.

6.2] What we are going to do is to sand the cylinder almost completely away so it just barely goes into the hole to locate/position the assemby.  Before that, I would recommend removing the catch from the bottom by pressing out the pin and removing the assembly.  Be careful with the spring – mine launched into orbit and I never found it so I used a second one off my spare kit.  Note, you can’t order this spring – you have to buy either an entire stock assembly or just the bracket if you can find it.  I bought a third stock assembly and the moral of this story is to carefully catch that little spring vs. letting it launch.  Note, the next photo shows it after I drilled and sprayed Molyresin on the part but I wanted to share a close up of the sanded down cylinder.  I have a big 2×72 grinder (sander) that I use for knives that makes this work very quick.  Just take your time and sand it square.

6.3] Next I took a folding stock mounting nut and ground it down until it just barely fit in the receiver hole from the inside.  This nut is tapped for a 1/4-20 screw so this made sense to me.  I carefully center punched the middle of the cylinder and drilled it with  9/32″ bit to give a bit of wiggle room to line up with the mounting nut.  Again, the photos are after finishing.  I went this route as the bolt buffer has a channel at the bottom that allows room for this nut and the dimensions had already been sorted out.  I bought the folding stock nut from Robert RTG.

6.4] I have a lot of 1/4×20 button head screws so used one of them to attach the bracket and then drilled a recess in the stock to allow it to fit.  I simply stuck the stock on the bracket and marked where to drill a 1/2″ recess.   The intent is that the bracket can’t be removed without first removing the stock.  A 1/4″ alloy bolt can handle a lot of sheer stress as can the thick receiver – that bracket is no longer quick anything.   Also, it took a lot of filing and fitting to the the front of the stock bracket to slide under the grip frame lug on the receiver and I intentionally left the fit very tight to avoid slop.  This was just a test fitting as I still needed to do the front screws on the stock.

6.5] In looking at the stock and bracket, I decided to countersink the wood from the bottom and insert screws from the bottom.  This is not a traditional look but I don’t think it messed the lines up too bad.  The one point I did pause and think about was limited material to thread into on the bracket.  Because the Israelis recessed the screw head holes, I had about an 1/8″ of material to thread so I debated welding the holes closed and then drilling and tapping new ones.  I decided to skip welding for now and give it a go with bigger 1/4×28 NF flat head screws that I turned down the heads by chucking them in a hand drill and pressing the spinning screw head against my spinning sander.  This trick works great by the way. I used a 1/2″ counter sink and a 9/32″ bit to open up the two stock holes.   The holes in the bracket were opened up with a #3 cobalt bit and tapped with a quality 1/4-28 tap with cutting oil.

The second photo below shows the front hole opened up and then I did the same to the second one.  The result seems very solid and I can always go back and weld the holes shut and start over if I have problems though I doubt I will.  A 9mm doesn’t have much recoil, the Uzi is actually pretty hefty and the inertia will soak up the recoil plus I will be shooting this as a semi-automatic.  I do not expect a ton of stress on those two screws and big top wood screw and recessed tang pushing into the surrounding wood will bear the brunt of it.

I then inserted the screws, tightened them down and used the sander to make them flush with the bracket.  I then disassembled it so I could apply the Molyresin finish later.

6.6] The stock was ready to go other than one minor detail – the sling swivel was a bit bent so I installed the brass protector plates on my vise’s jaws and then tightened them down on the wire loop to straighten it out.

So at this point, the stock was done.  I had it in pieces waiting to apply the Molyresin finish that I will cover in post six.

It’s a bit out of sequence but for folks just reading this post about the stock, here is the end result.  With the new permanently attached stock, the overall length is a safe 31″.  Here are some up close photos of the finished product so you can see how it turned out:

Uzi Part 2 of 7: Stripping the Parts Kit

Now there are parts you need from the kit to do your assembly so let’s step through them.  I would highly recommend that you have a means to organize your parts and not lose them.  Zip-Loc bags, parts tray, etc.

Also, another fellow did a great write up on his disassembly – click here to read it.

1] Remove the handguards – they are held in place by two slotted screws.  I highly recommend you always use gunsmith/hollow ground screw driver bits that fill the whole slot of a screw to avoid tearing the screws up.  These screws are not under much torque and mine very readily came out.  You may want to replace these with new handguards.  Mine were in tough shape due to being bounced around in the parts kit bag.

2] You will need the front sight assembly.  It is comprised of the inner sight itself, a locking nut and a washer underneath.  A real Model A Uzi front sight tool makes a world of difference as you can easily loosen the locking nut and then unscrew the whole assembly.

 

3] Remove the barrel nut catch assembly.  It is comprised of the catch itself and a spring.  Reach in from the rear under the sight, push the tab down with your finger and pull the assembly out.  You can do this with your fingers.  If you look at the first photo in step one, you can see the catch still in the old receiver stub – it is the L-shaped protrusion over the threads.  You’ll notice the new receiver (which is still in the white in these photos) does not have it.  Now, in the second photo, if you look at the old stub on the right you will see the tab of the catch sticking out – this is what you push down with your finger while pulling out of the front.

4] You will need to salvage the front sling swivel.  I sanded mine down flat, center punched the middle of the rivet, start with a small 1/8″ drill bit and worked my way through larger and larger bits until the swivel separated from the old rivet.  I then used a punch and removed the remnants of the old rivet from the center of the swivel.  By the way, I’ll tap the sling and mount it with a button head screw and Loc-Tite in a later post.  Don’t worry about tracking down a replacement rivet and squishing it unless you really want to.

5] Remove the rear flip sight assembly.  Now, there is a slotted screw on one side and a tiny nut on the other.  Be careful when you loosen the nut as it will come right off.  I used a long punch to push the screw back far enough to then grab the screw and pull it out.

6] The next step removes the top cover catch.  The rear sight spring actually covers the catch assembly so just pry the spring upward and you will see the top catch and the captive spring.  Now be careful – this spring will launch if it slides over the rear lip so carefully remove the top catch itself by sliding it out the front.

7] You will need the barrel nut.  Mine was in a small bag in the parts kit.

8] You need the top cover.  Now I bought a modified one with a picatinny rail attached.  If you use the original cover, there is a small wedge called the “cocking pawl” that you will need to remove.  My cover was lose in the bag so I just set it to the side.

9] You will need the return spring assembly but you will need to cut the buffer plate off at the end of the guide rod.  I just took a pair of diagonal wire cutters, made one snip from the side and it literally came right off the return spring guide rod.  Be careful not to bend the guide rod – you will use this spring assembly with the new bolt.

10] You need two things from the submachine gun open bolt.    Put the bolt on a bench block and push/tap out the extractor retaining pin from the side of the bolt – tap/push on the small side with a punch.  The extractor looks like a screw from the rear end of the bolt but it actually presses right out.  Push from the end with a punch or small screw driver and it will push right out the front of the bolt face.  Note, the slot is so you can use a screw driver to rotate the extractor into proper position when you install it.

11] In my parts kit, the entire grip frame assembly was in the bag.  Now there are some critical changes that must be made to it but for now, set it to the side.  The grip panels were chewed up so I bought a new set of those along with handguard panels.

12] You need the complete wood buttstock assembly with the entire wood stock mounting bracket system and all the hardware on the stock.

That’s it for now.  The next blog post will get into the details of how to refinish the wood stock plus permanently attach it.

Israel, Uzi Builds

Uzi Part 1 of 7: The Uzi Kit, Receiver and Barrel

One of the firearms that had an impact on me growing up was the iconic Israeli Uzi.  In the 1980s you would see them in the news, TV shows and movies all the time.  Today, being quite a bit older, what interests me is the history and engineering that led up to this weapon.  Suffice it to say that Israel has known conflict even before the country was founded in May 1948 and certainly ever since.  Israel first fielded the Uzi in

I’m not going to duplicate the history as there are some excellent resources out there that explain the political climate and how the Uzi came into being.

  1. The first is a book by David Gaboury entitled “The Uzi Submachine Gun Examined” that is the single best reference guide I found. I can’t recommend it enough and you will not regret buying it.
  2. There are three overview videos on Youtube that provide good context – especially if you prefer watching  a video to reading.
  3. The Wikipedia entry provides a decent overview as well.

The Uzi has evolved into a variety of weapons including the micro uzi, semi-auto versions and so forth.  What interested me was the full size Uzi that I had grown up hearing so much about and you’d see them with the original wood stock and the metal folding stock.

Over the years, I’ve made many AKs and ARs for personal use.  I’ve been really busy but wanted to build something different.  For the past several years I have noticed that there are a ton of Uzi kits for sale from the various parts kits vendors and this sparked my interest.  For me, part of the challenge of building from a kit is learning how to do so legally and finding all the parts.

I knew I wanted to build a carbine vs. a pistol so that shifted me in the direction of a wood stock for a number of reasons:

  1. To be classified as a rifle, the barrel needed to be at least 16″ with an overall length of 26″.
  2. To get the overall length, that meant I either needed an even longer barrel or a permanently attached stock that would surpass that 26″ minimum.
  3. The resulting carbine would be front end heavy and the wood stock would help balance things out.
  4. I am not a huge fan of my cheek being on sheet metal – I prefer wood with a gently bend.

Now you many have a different perspective and that is just fine but due to this I ordered two wood stocked Uzi kits from Robert RTG.  I only planned to build one Uzi but purchased a spare kit for donor parts just in case.  What arrived were two seriously oiled kits.  The wood was a tad beat up as were the pistol grip and handguard panels – probably from being packed with the parts.  The bolt and fire control group honestly looked like new.

In terms of the receiver, all my research pointed me to buying one from McKay.  They offer just the bent receiver shell and you can do all the welding or a fully welded receiver that is all set for semi-auto use and ready for you to assemble with.  I opted for the ready-to-go model and based on McKay’s reputation, I also ordered my 16″ 1:10 twist 9mm NATO chambered barrel from them also.  I placed my order direct with McKay, had them ship it to my FFL, Scott Igert, and it arrived a week later.

McKay really did a real nice job on the receiver.  Here it is with some of the original stubs sitting by it:

Here are the details that McKay took care of when they make their fully welded receiver:

  1. The front trunnion has a reduced inner diameter to prevent installation of a military model
  2. The rear barrel support ring must not allow a military barrel to be installed
  3. The bottom of the semi-auto feed ramp will block a full auto sear – in other words, it is just a tad too long for the full length original sear to fit.
  4. The right side of receiver behind the ejection port has a block bar welded in place that prevents the installation of an original full auto open bolt.

The other plus is that everything above is American made so that means the receiver and the front trunnion count as US-made parts.  By the way, in terms of 922r, an Uzi has 13 parts on the 922r parts list so that means three must be replaced with US parts to meet the maximum limit of 10 foreign parts.  The McKay receiver, front trunnion and US-made barrel will enable you to meet the parts count requirement.

By the way, there are a lot of other posts about how to do an Uzi:

For Uzi parts, my go-to sources are:

At any rate, let’s wrap this post up and will discuss the the parts you will want to remove from the old kit.

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.

Britain and the UK, Sten, Uncategorized

Video: Forgotten Weapons: British Submachine Gun Overview: Lanchester, Sten, Sterling, and More!

I have lately become very interested in sub machine gun class weapons, or SMGs.  I’ve built a number of 9mm ARs over the years and while they are interesting and fun to shoot, there’s not much history to dig into.  So, I have been researching British Stens for a while now and the history that led up to them and the thinking behind “good enough” to get the job done vs. perfection is fascinating.  It’s really intriguing when you see what folks can create when expediency is the name of the game.

To launch the series, I am posting this awesome video from Ian over at Forgotten Weapons.  He always does an excellent job researching what he is going to cover and then walking the viewer through what he is presenting.  In this video he provides an overview about the British Lanchester, Sten and Sterling.

Germany plus Historical East and West, Russia and also USSR, Sniper / Precision Rifles

Video: Ostfront 1987: Walther WA-2000 vs SVD Dragunov from InRangeTV

This 30:11 long video had me seriously drooling.  You have Ian McCollum from Forgotten Weapons and Karl Kasarda from InRangeTV squaring off on targets.  Ian is firing a rare German Walther WA-2000 sniper rifle in .300 Win Mag and Karl is shooting the Russian 7.62x54R SVD Dragunov.  They role play a bit and take this back to the Eastern Front of 1987.  I think both rifles are amazing and both presenters do a great job.  It’s very cool to see what the rifles can actually do vs. armchair myth.  Kudos to both men!

Here’s The Video

Germany plus Historical East and West, Sniper / Precision Rifles

Video: Walther WA-2000: The Ultimate German Sniper Rifle by Forgotten Weapons

The first time I saw the Walther WA-2000 I fell in love.  Wow.  It was the most amazing looking sniper rifle I had ever seen and I’ve only seen one once years and years ago.  Like the HK PSG-1, the WA-2000 was developed in response to the 1972 Munich Olympic Games incident.  Development started in the lates 1970s and only 176 rifles were produced between 1982 to 1988.  When it was sold in the 1980s it never really took off because it was incredibly expensive – only 15 were imported into the US.  The one I saw was around $10K if I remember right.  Today, the price has skyrocketed – $70K for the first gen with the wood stocks and $40K for the second gen with the synthetic stock.  With prices like that, unless I hit the lottery, the odds of my owning one is zero 🙁

I watched Ian’s video on the WA-2000 and, as usual, he does the best review of the rifle I have seen.  He goes over the history, interesting design characteristics, disassembles it and then takes it shooting.  Wow.  I would love to shoot one of these.  One misconception I had before the video was that the rifle was only chambered in 7.62X51 when it was actually available in .300 Win Mag and 7.5×55 Swiss.  The rifle in the video is a .300 Win Mag unit.

Here’s the cool 23:49 video from Forgotten Weapons:

Iraq, Military

Video: Rare Weapons of Saddam’s Iraq 1979 to 2003 by jmantime

       

I like jmantime’s videos – lots of photos, organized and set to music.  He assemble this video around the weapons found in Iraq during Saddam Hussein’s reign between 1979 and 2003.  The video ranges from Tariq handguns and Tabuk rifles all the way up through through tanks, the Babylon Gun, rocket launchers and so forth.  This video is only 14:39 video and worth the time given all that he has assembled.

I mainly focus on firearms:

  • Tariq 1, Semi-automatic pistol, 7.65x17mm
  • Tariq II, Semi-automatic pistol, 9x19mm
  • Tabuk, Assault RIfle, 7.62x39mm  [Their licensed version of the Yugo M70]
  • The Golden Tabuks they found in palaces
  • Tabuk, Designated Marksman Rifle (DMR), 7.62x39mm
  • Al-Kadesih, Semi-automatic Marksman Rifle, 7.62x54R [Their version of the Dragunov]
  • AI-Quds, Light Machine Gun, 7.62x39mm [Their licensed version of the Yugo M72B1]

From there it covers tanks, self-propelled guns and so forth.  All in all, it’s a neat video with lots of photos that jmantime collected.
