I am so glad that I found this video. I wanted to do exactly this but I wasnt sure if the Polymer and steel shaft were the same pin size and would fit on an AKS-74
Glad you found it helpful. Yeah, so long as the stock you want is the same pin diameter (4.5mm/5.5mm) as the one on your rifle then you're all good to go.
As others have commented clear and concise instruction with great lighting. Very easy to understand. You need to make more instructional videos! I am relatively new to AKs and I have a M92 PAP clone built on a Nodak receiver but it has a side folder. Does that mean it has a side folder trunion in the back and how to tell if its 4.5/5.5mm pin ?
The easiest way to tell If you have a side-folding trunnion would probably be to fold the stock and if you don't have a steel tang hanging out when it's folded, that would indicate you have a side-folding trunnion. Otherwise, there are a lot of folding stocks now that adapt to the fixed trunnion, so if part of that trunnion sticks out, then it's usually a good indication it's a fixed vs. folding. As for whether it's a 4.5/5.5mm pin, I'd recommend using calipers to measure it. Here's also a link to an image showing the visual differences between some 4.5 and 5.5mm pins, which can help determine which one you have. imgur.com/FlWppX4
I believe the AK-103 uses the 5.5mm pin. I found an image that shows some of the visual differences between the different pin sizes. i.imgur.com/FlWppX4.png Hope that helps.
Mine is so tight in there... I was banging so hard , I was afraid to break the Krink 😆 Took of dust cover folded the stock, still no luck. I'll try to soak it in ballistol and try again.
Can you please explain what that BUTTON is on the back end of the solid stock? I keep seeing that thing on these AK stocks and it looks like something that would dig into your shoulder. What is that and why is it there?
The button on the back of the solid stock is what you press to unlock the stock when its fully folded. On the triangle stocks you can manually pull the locking lever out and move the stock back into place, but since that's impossible on the solid stock that's the solution they came up with. It doesn't dig into the shoulder at all. The button depresses very easily, so when you have it shouldered the button just moves into the stock and out of the way.
Nice video!! Where i can buy a 5.5pin in Europe. My pin want come out so we Drill them, it was realy Tight its a Saiga MK106 wir 5.5mm. Did someone has a idea????
Same, except I have the California version so I can't even try positioning it differently. After days I have 0 luck, my 300 dollar JMac stock is just sitting there
This is the same type of stock I got in mine, it is a PSA GF4 with voodoo furniture but it comes with that awful metal stock, now I did get the zhukov-s stock and seems it is NOT compatible with this rifle; I do not see how to mount it on it and that would suck because I do not like at all that cheap metal stock!
The Zhukov-S is completely incompatible with side-folding receivers. I believe PSA uses a 4.5mm pin, so you'll need to find a 4.5mm side folding stock like the Bulgarian or AKS-74U-compatible stocks.
The PSAK-74 uses a 4.5mm pin, there's a visual difference between how the hinge section is set up between 4.5 and 5.5 which can be seen in this photo: i.imgur.com/FlWppX4.png
@@Feldmutze It's a CYMA one pretty close to the Real 74M. All the details everything. Altough the dust cover is ribbed the details spot on. Also thanks for reply man. I dunno the stock little wobbly.
I would try using solvents to try to clear any blockages that might be there and try hammering it out again. Also try hammering it with the stock unlocked at different angles as not every stock, pin, and locking mechanism is perfectly in spec so at some angles it will be looser/tighter than others. As an absolute last resort you can drill the pin out on a drill press though you will need to replace the pin then.
I'd look at other stocks, the Magpul stocks as far as I'm aware are made to fit AKs with a fixed rear trunnion so adapting a side-folder wouldn't be possible.
I had that issue when I was installing a Zenitco PT-3 stock. You can fix it by cutting out a bit of material in the "0" sort-of shape where the stock is held in. A little hard to explain in text, but I showed it in a video I did on the installation of the PT-3 stock in specific, which I'll link below here. The specific dremeling part is at 11:04, though the link should automatically go to that time. ruclips.net/video/K1LbiO5UVHw/видео.html
I don't own one but from the looks if it, no. It looks like the ZHUKOV-S only fits the older style fixed rear trunnions. I think the only difference between the ZHUKOV and -S is the -S is made for Yugo rifles.
The triangle stock I have is just one that my SLR-104FR came with from the factory. As for where to get one, you could try SovietStocks or RussianSurplus which both have triangle stocks for 5.5mm pins available, but I'm not currently sure where to find a 4.5mm triangle stock currently as all the usual places are out of stock. You could try GunBroker but that's always iffy.
straightforward and to the point video with clear instructions and good lighting. Everything anyone could ever ask for from a how-to video. 🤘🏻 I’ll be swapping my polymer stock for a Russian triangle folder once it arrives in the mail. Thank you for the help. Looks pretty simple!
It's an ATI X1 grip. Works pretty well on fixed stock AKs but I had issues with it on this SLR where it pushes my thumb into the hinge on the side + it broke on me so I wouldn't recommend it. I'm now using a Custom Arms AG-74 pistol grip that's being working really well so far.
ATI X1 grip. I wouldn't recommend it as it has a very uncomfortable overhang if your AK has a reinforcement plate for the grip, and the polymer is quite weak and mine broke a few months after this video.
How hard is it to install the whole folding stock assembly, would it required me to go to a gun smith/ gun store and have them install it? Would I also have to remove the rear trunnion with the rivets?
I was considering doing the same thing on my old AK-74. Installing a new folding stock assembly from a regular solid stock is a very involved process that I personally would recommend against doing. It's definitely something you'd want to take to a gunsmith if you do. You would have to remove the old rear trunnion and the receiver would also need a few extra holes drilled into it. One other thing I'd like to point out with installing a folding stock assembly is I don't think you can put the stock locking latch into the receiver, I could be wrong on this point but I never saw it done personally and I know Arsenal's folding stock assembly they sell does not include the locking latch. Sorry this was quite a long comment but hopefully that helps.
@@Feldmutze I figured as much. I would think it would be easier since my receiver is stamped vs milled, but I'm pretty sure it will still require a professional to install it. I guess my next route, until I figure if i want to go through with it, would be getting the folding romanian wire folding stock. It'll fit right into the rear trunnion where the old wood stock was.
If you have a triangle stock then you manually pull the locking lever on the receiver, on other stocks like the one I replaced mine with you push the button on the back of the stock which pushes the locking lever out of the way so you can unfold it.
The process itself is the same for an RPK though side-folding AK stocks may not fit on a RPK because RPKs are supposed to have a different receiver thickness.
It'd be *really* involved to switch a WASR to a side-folding stock. If you do change it though you could use whichever pin size you find stocks in since it'd require replacing the rear trunnion at the least.
@@KevinPerez-rv6bx It's pretty hard to do in my opinion. And unfortunately side-folding wire stocks don't use normal pins like the ones I showed in this video so you wouldn't be able to just put a triangle stock where the wire stock used to be. If you want a triangle stock I think you're much better off buying a different AK with a side-folding receiver & trunnion already on it.
Yes. I know Armacon sells an AR-to-AK tube adapter and you can probably find some American manufacturers that make a similar product. Just make sure you find one with the right pin, the Monolith I linked might only work on 5.5mm pins which I'm not sure if PSA uses. ivantactical.com/shop/weapon-accessories/weapon-rails-and-tuning/buttstocks/armacon-monolith-3-gen-2-ak-folding-buttstock-to-ar-15-tube-adapter/

@@BenThomson887 I'm not too familiar with airsoft guns so I can't really help there. I know some airsoft guns are made slightly different from their real gun counterparts, so perhaps there's information specifically for your model out there?
@@BenThomson887 Oh gotcha. I mentioned this is another comment too, but the new stock I installed here in the video was a lot tighter of a fit than the first stock and I had to hammer it in a lot (though I cut out the footage of the more difficult part). So you could try hammering it in if it's the pin that isn't going in, unless it's a different part of the stock that isn't fitting?
@@romeorifles300 Congrats! It's a great rifle so far in my experience and I'm sure you'll enjoy shooting it, 5.45 is a very comfortable caliber to shoot.
If the pin doesn't come out easily it probably the stock fits on the tight side or, much less likely, that the pin is slightly bent. The simplest solution I can think of is to cover the pin with something so you don't damage its finish or surface and hit it really hard. Otherwise you could try jury-rigging a vise or something of the sort to push the pin out, though that would probably be more effort than its worth.

Have you ever had the stock not lock in the extended position? My PSA-103 is doing that.
I've never had that issue myself. I've heard of some issues people with PSA's stocks so I'd presume it to be a quality control issue on their side.
Trying to remove that pin on KUSA kr9 is a nightmare. Im litterly beating on it(using a punch) with a hammer and and would not go out.((

Is this the 74M model? What size are the Muzzle Threads?
The AK in the video is an SLR-104FR, which is more-or-less a civilian AKS-74. The muzzle thread pitch is M24x1.5.
Does AK103 flooding stock version take magpul ZHUKOV-S stock?
I don't own one but from the looks if it, no. It looks like the ZHUKOV-S only fits the older style fixed rear trunnions. I think the only difference between the ZHUKOV and -S is the -S is made for Yugo rifles.
do you know if its possible to put a fixed stock on a side folding stock model?
It's not possible without significant modification to the fixed stock and adding a hinge to it.
