Video: Forgotten Weapons Reviews Soviet AK Magazines

In this short video, Ian gives a brief overview of Soviet magazines – notably the slab side, ribbed, waffle and bakelite. As always, Ian does a great job and this is worth a watch!

The first generation was a heavily built (over-built) magazine known as the “slab side”.
After the slab side, they developed the ribbed magazine that was copied by many countries.

To reduce weight they developed the aluminum waffle magazines- so named due to all the reinforcement ribs. It was relatively short-lived because it was not durable enough.
After the waffle mag, they moved to the Bakelite magazine that actually was a glass reinforced polymer. This gave them what they wanted – light weight and durability.
When the AK-74 was developed, they went straight to polymer and never developed steel mags. Note, other countries did build steel AK-74 magazines but the Soviets did not.

Video: Apex Gun Parts’ Croatian AK-47 Magazines Being Manufactured

While digging for videos on AK magazines, I found this one posted by Apex Gun Parts in 2016. It shows their Croatian AK-47 magazines being manufactured. While they don’t come right out and say they are being made by Zastava, I have a hunch that they are.

I would like you to compare this video to the one I previously posted showing Matra Group’s process. Matra is using older general purpose machines and there isn’t much attention paid to worker ergonomics and lighting.

Now, watch this video and not the differences. This video is showing a much more modern plant where there is also detail provided on their quality control processes and they show the jigs that they use.

The Video


I hope you find the video interesting. Apex Gun Parts is definitely a group that I buy stuff from and have no problems recommending them. I don’t have any experience with these mags so this video is really to let you see the differences in manufacturing.

Video: Matra Group Manufacturing AK-47 and AK-74 Steel Magazines: From Sheet Metal To The Finished Products

The AK-47 rifle and it’s “banana” 30 round magazine are classics of rugged functional design. While I’ve posted many videos and how-to articles relating to various rifle and pistol variants, I’ve not really covered the steel magazines at all.

I was surfing around and found Matra Group located in Bosnia-Herzegovina. In 2015 this small manufacturer produced a video showcasing their small facility that makes a variety of steel magazines for AK-47, AK-74 and even Lee-Enfield rifles. The Lee-Enfield may be due to those rifles being supplied to the Yugoslav Partisans in WWII to fight th axis armies.

In the video, they show employees starting with sheet metal and stepping through various steps including stamping, machining and spot welding. For the most part, you will see a very labor intensie process using older general purpose machines. If you like videos that showcase how something is made in and old-school fashion, you will find this very interesting.

Here they are cutting the initial sheet down into usable blanks.
Making the front piecee that will lock onto the front trunnion.
Spot welding the two body halves together.
Gettingg ready for final assembly.

Here’s The Video


I hope you enjoyed the video! I definitely found it interesting and informative. Just to be clear, I am not endorsing the magazines – I’m just showing their manufacturing process so I can then compare it to the manufacturing used to produce the Croatian AK-47 magazines that Apex Gun Parts sells.

Assembling an AR Lower – Step 1 of 11: Installing the Magazine Catch Assembly

Just a quick note – when you get a bare receiver, you are literally getting a chunk of aluminum with nothing installed.  I really like Palmetto State Armory (PSA) lower build kits and they sell them with different types of components such as just the basics for rifles, for pistols, Magpul furniture, etc.  What I like is that the machining is very good and I think they have some of the best Mil-Spec basic triggers that aren’t gritty.  I’ve used Anderson and other brands of build kits and just think the PSA kits are superior.  Bear in mind that I say this as a customer – nobody paid me to tell you this.

With that said, let’s start building.  You’ll notice on any AR magazine on the right side there is a rectangular notch.  This is where the magazine catch engages to hold it in place.  Okay, so the first step is to install the magazine catch assembly.  It’s made up of the “L” shaped catch itself, the mag catch spring and the magazine button.

   

Now I grease everything that slides with Tetra Gun Grease.  Tetra has worked well for me but I also know guys who use all kinds of greases.  As a rule of thumb, if it slides, apply grease.  It it rotates  then apply oil.  So grease the shaft and insert it into the round hole on the right end of the recessed area for it on the right side of the receiver.  Note, be careful when installing the catch or you may scratch your receiver.

When you turn it over you will see the threaded end of the shaft and you put the spring down over it.

Next, you will screw the magazine button onto the threaded shaft.  Before you do, look at the button.  You should see that one end is smooth (that is the bottom) and the other has grooves (that is the top).  Carefully start screwing the button on but stop before you get near the receiver so you don’t scratch anything. Push the button in, and then turn the long lever arm to continue threading the shaft into the button.  Now stop before the lever arm scratches the receiver.

To screw the catch in the rest of the way you need to push the bullet button in all the way so the catch sticks out as far as it can on the other side so the lever arm can clear the parts of the receiver as the button is screwed on.  At this point, I use a small pusher tool made from plastic to push the button in even further so I can keep turning the lever arm until the screw is relatively flush with the top of the button.  Note, before I had the tool I would use a wood dowel.  Just use something non-metallic to protect the finish.  There is a model of the tool shaped just like the oval button but I don’t know where mine went so I used a takedown tool and got the job done 🙂

The catch is now installed.  To function test, push the magazine button.  You should feel spring resistance and see the magazine catch’s lever arm push out.  When you ease off the button, the lever arm should smoothly go back into place.

Sluggish Marauder Mag Fix: Try #3 – Change the Internal Spring Position – This is the best fix!

Please note that there are three posts in this series.  The method in the third post would fix just about any magazine while the other two helped some of the magazines:

  1. Sluggish Marauder Mag Fix:  Try #1 – Loosen the Center Screw
  2. Sluggish Marauder Mag Fix:  Try #2 – Dry Film Lubricants – Not a Good Fix – But Avoid 3-In-1 Dry Lube Because It Isn’t Dry!
  3. Sluggish Marauder Mag Fix:  Try #3 – Change the Internal Spring Position – This is the best fix!

Now on to the post:


Ok, in the first couple of tries, I had some success loosening the center screw on a couple of the sluggish mags.  Marginal improvement with dry lube but that didn’t fix two.  What resurrected the two worst magazines was to disassemble the magazines and move the spring’s anchor leg to the center hole.   What this did was to increase the tension of the spring and boy, did that fix the problem in spades.  In the future, I would try loosening the center screw and if that didn’t work, I’d go right to this spring adjustment:

Here are the steps:

  1. Note where the spring is at currently my looking in the holes in the back of the magazine.  If you see metal, that is the leg of the spring.  All of my mags have had the spring’s leg in the same place from the factory thus far:
  2. Remove the center screw and disassemble the magazine with a 1/16″ hex key.  Pay attention to how it fits together and also look for any debris or burs that might be causing drag:   

    In this next photo, look at the spring.  The downward leg is the bottom and the sideways leg is the top and the center of the drum has a slot that the top part of that spring nestles into:


  3. Move the drum’s spring to the center hole in the track where the pellets are carried.  . See the oily crap … I mean “film” in the mag?  That is courtesy of the 3-in-1 supposed dry lubricant that I will never use again and got cleaned out right after I took this photo:
    If you aren’t sure what hole I mean, look at this next photo.  Magazines PA2 and PA4 have the spring located to the new hole half way around the magazine track.  PA1 and PA3 still have the springs in the original hole and seem to work ok.  This is also a good example of how labeling your mags helps you keep track of what is going on.  PA1 was the worst by far.
  4. Align the drum with the top of the spring and then carefully rotate the assembly clockwise slightly angling the long part of the drum so it will clear the part of the magazine that forms the start/end of the magazine area that holds the actual pellets.

  5. Install the top so the brass pin that is embedded in the clear magazine cover rides in the groove of the drum.  I slide the cover on upwards from the bottom while keeping the center secure otherwise it will fly out.
  6. Re-install the screw.  Tighten it down until the cover can’t lift up and adjust the screw in/out until you feel the right amount of tension on the cover and it can move.
  7. Test by turning the top – you should feel way more spring tension now.

So in my testing, this worked great.  If just loosening the cover a bit works for you, then great.  If not, take it apart and move the spring.  Note – I did try spraying the good Dupont Teflon dry lube in one of the magazines and I can’t say that there is a noticeable difference.  You can if you want to experiment, but I’m not going to bother going forward.

I hope this helps you out!

  3. Sluggish Marauder Mag Fix:  Try #3 – Change the Internal Spring Position – This is the best fix!

Now on to the post:


I just bought eight brand new .22 Marauder magazines for my BNM breach and about half of them were sluggish. In other words they didn’t really want to come back around and feed the pellets the way they should. In closer investigation, some had been over tightened during assembly. I simply backed the cover screw off with a 1/16 inch Allen key and that easy change did help a couple of the mags but not all. I would turn a little bit and test, turn little bit and test, etc.. I bet I backed off less than 1/4-1/2 a turn for the magazines that had problems.  It didn’t fix all of them.  Two were still sluggish.  This is quick, easy and worth trying if you have a problem:

Note, the allen screws uses a 1/16″ key:

The other recommendation I would make is to use a silver Sharpie pen and label your magazines so you can keep track of how they perform. I’m also experimenting with spring position some and will write that up in another post. I have started putting a silver dot on the factory spring  hole.  So far all eight were in the exact same hole.

Frankly, I think they went with a cheap design.  I still have two things I want to try – using a dry lube and changing the internal spring position.  These will be in my next two blog posts.

What to do if your Marauder Rifle Magazine is too tight in the BNM breech

My magazine was a bear to pull out from my CP1002 BNM breech.  I talked to Sergei at BNM about the tight fit and told me that they keep they keep their tolerances tight on purpose.  He would rather things be tight vs. loose and that makes sense to me.  So if your Marauder magazine is a bear to push in and out of the breach, a tiny bit of fitting is needed.  The bottom of the Marauder magazine can be lightly sanded to allow magazine to be inserted easier.  It probably is not the front to back dimension that you need to worry about so try the following first.

All you need to do is get some 320 grit sand paper, rub the bottom lightly, evenly and test.  You just need to do the part that slides into the receiver.  320 was all I needed it took off enough to do the job gut also left a fine enough finish.  Another benefit for those of you that may be nervous is that it can only take off a small amount of material.  It will fill fast so with each pass, use another exposed surface of sandpaper.  That is why you see two ends used on the second photo.

For mine to fit way better, it was just a tiny amount I had to take off.  So don’t go crazy and take off a too much too fast.  Literally, do 4-6 rubs, blow it off and test.  Do this until it fits.  I think I did all three of my mags with just a couple of rounds of sanding and testing each.

I could have sanded it with 400 grit and even gone up to a polish but just doing 320 seemed to work great so I stopped there.
