The typical semi-auto AK trigger has four parts – the trigger body, disconnector, disconnector spring and pin. Installing it can be a challenge because you need to properly align the disconnector while sliding the pin through from one side of the receiver to another. For me, with big hands, this task takes more effort than I want.
This is your typical semi-automatic AK trigger group. On the left is the trigger body, top right is the disconnector, under the disconnector is its spring and at the bottom right is the trigger pin. The challenge is getting this all assembled inside of the AK receiver as the pin needs to pass from one side of the receiver, through one side of the trigger, through the disconnector to capture it, out the other side of the trigger and finally out the other side of the receiver. Trying to get it all to align inside of the trigger takes some patience.
The Solution – Use A Slave Pin
There is an easier approach. We can slide a properly sized dowel pin to serve as a “slave pin” during assembly to secure and properly align the disconnector and trigger outside of the receiver. This simplifies life tremendously. The unit is assembled outside where you can see what is going on, is lowered into the receiver and then the actual trigger pin is pushed through and it displaces the slave pin – the slave just exits the other side of the receiver.
This is the slave pin. Note how one side is beveled more than the other. That is the side that is inserted first. The bevel helps move things around during insertion and then the 5mm body provides the actual alignment for the trigger pin.This is the assembled trigger group with the slave pin holding it all together.Normally this would be in the receiver but I want you to see what is going on. As the trigger pin is inserted, it pushes the slave pin out of the way and it exits via the opposite receiver hole.This photo shows how when the trigger pin is fully inserted, the slave simply drops out.This is an ALG semi-auto trigger and you can see how slave pin is exiting the receiver as the trigger pin is installed. So there’s the end result. A slave pin makes a world of difference. Note, that is one if our fire control group plates retaining the trigger and hammer pins.
If you’re like me and want an easier way to install AK triggers, these new slave pins are the way to go!

You know, it’s interesting how people will argue over stuff on the Internet. Give them a picture of a stick and they will argue about it! Now, turn the topic to AK rifles and debating what is the right or wrong way to do something, things get colorful fast and a lot of energy is wasted over trivial points.
In this video, Vladimir Onokoy, who always does a great job, goes over different reloading approaches. Now most folks do not know Vladimir but I will tell you he is the real deal with considerable Russian military experience and armorer-level experience with the AK platform. In short, I would recommend you listen real close to what he says plus bear in mind that this is a Kalashnikov Media video and they know their stuff as well 🙂
Watch the Video
Normally I give some screen shots and make some color commentary but this video is only 3:05 seconds and seeing is believing.
I fully agree with his conclusion – train and become proficient. They all work the question is what works best for you and only training and experience can answer that.

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.
