SIG Stock Adapter for AK-47 Rifles by Aeroknox

Aeroknox released on their Facebook page some images of a new product which is still in development and isn’t yet available on their website. They are developing a rear trunnion for AK-47 type rifles, which provides a Picatinny rail section as shown in the picture below. That feature allows attaching SIG MPX/MCX stocks to AK rifles.

The new rear trunnion prototype is machined out of a solid block of aluminum. In order to install it, you need to remove the existing rear trunnion rivets, uninstall it, then install the Aeroknox trunnion and fix it in place with new rivets. As you can see, it is not a drop-in accessory. You either need to have proper tools and skills to install the rivets or take it to a gunsmith to do the job. You know, one of the most (if not the most) important portions of building AK rifles is to properly install the rivets.

Aeroknox LLC has been involved in the development of the 5.56 Microgun (a hand-held 5.56 caliber version of Minigun). Obviously, that kind of guns are rather marketing projects to attract attention to a startup company. However, Aeroknox has some interesting (and useful) products already developed, which at least look great. Some of them like the hand stop and the AK grip are shown on the pictures. You can see more on their website.

Hopefully, we’ll see this stock adapter made available for purchase soon.

    I will admit that it looks damn good, but I don’t know who is going to go through all of that trouble when you can just install a magpul zhukov for a lot less time and probably less money.

      Because that stock is poopy. The CNC Warrior Galil clone stock is pretty much perfect. The CNC Warrior stock as the advantage of just slipping into the tang rear trunnion.

    Gross two things nobody wanted. Sig stocks and keymod.

      The beauty here is, easy pistol to SBR conversion after you get your paperwork.

    “The new rear trunnion prototype is machined out of a solid block of aluminum.”

    No, thank you! The rear trunnion of an AK is made from decent steel for a good reason, namely that it takes quite an impact from the carrier. Now, if they produce them in a decent steel instead of easy-to-machine 6061 or similar, I could see the appeal. But aluminum for a part meant to endure impact stress like that? Not a good idea.

      Oh man, it’s almost like this is a prototype or something that they want to do function tests on and make sure there’s actually interest before they bring something to market.

      /sarcasm

  • $100 aluminum pistol grip? No thanks.

    “Nyet, Comrade! Rifle is fi…”

    Oh f*ck it!

    Always happy to see something new, but why didn’t they bolt a rail to the back of a flat pistol trunnion?

    There are entire companies built around that concept…and it would be a lot easier.
