There seems to be enough interest about the Cut-The-Tang receiver blocks for milled rifles that I decided to make a pictorial guide for the guys who don't know how to install one ...

Step 1)
Take a brand new, just out of the box Arsenal SA M-7 and inform it that it has fallen into the wrong hands and needs to be modified ...
This rifle was actually purchased for this particular modification ...


Step 2)
Remove the pistol grip and buttstock from the rifle ...


Step 3)
Cut the lower tang flush to the back of the receiver, file if necessary to smooth it up ...


Step 4)
Mark the upper tang about a 1/4 inch from the rear of the receiver, about 1/8 past the little ridge on the tang. Look at the ACE block and you'll see how far it needs to be. It's better to cut the tang long and take off more material if necessary ...


Step 5)
Cut off the tang and finish it with a file, the edges will need to be slightly rounded, use the block as a guide and test fit frequently ...




Step 6)
Blue the tang with your favorite bluing ...


Step 7)
Now we're ready to install the block. If you are going to use the folding mechanism then your good to go, just bolt it all together.


Step 8) Optional mounting ...
If you are not going to use the folding mechanism then the stock will be a little lower than the receiver when you mount it because of the way ACE does their mounting holes on this block. The easy fix for that is to just put screws in the existing holes with threadlocker and cut them off flush with a Dremel, then redrill and tap the screw holes, the sling swivel stud may need to be shortened slightly ...


Step 9)
Attach new badass Izhevsk grip and your favorite muzzle device, in this case it's the old style chicom RPK brake ...


Step 10)
Sit back and fondle your newest AK addition while watching the greatest AK oriented movie ever made RED DAWN ...

LOL, because ACE folding mechanisms flop too much when folded. They're not like the Russian/Bulgarian types with the hook ... :wink:

Besides I'm old and folders have lost their fascination to me, I want it all rock solid ... :lol:

i'm getting ready to do this to my SA-M5. thanks for the post. i was thinking of going with the folder, though. is there a way to keep the ACE stock from flopping around?

My sole reason for even posting this pictorial was because of all the questions I've received asking me how to do it, so there must be some interest in it ...

For the Purists:
I've had many AK's my lifetime, most all of them were stock from the factory and stayed that way. On some I adapted Galil sight rails to them long before we had side mounts available and now a lot of guys like to have a side mount, in the old days they were only found on Dragunovs. I was mounting Bushnell Holosights on AKs before the inception of the Eotech and the Eotech seems to have caught on rather well ...
Stock factory AKs are great but there's only like 100 million of them out there, I think there's room to try a few new ideas, that's how rifles like the Galil, the Beryl, the Krinkov, the AK 102, AK 104, AK 105 and Saiga 12 were born, because somebody somewhere had the balls to say "I wonder if this will work" and "butchered" a rifle to see if it would work ...

The bottom line is that this particular modification works very well for me as it puts my eye on target faster than using the standard AK stock which puts my eye a bit too low. This modification gives me a faster first shot and consequently faster follow up shots thus making me a more efficient shooter, which in my book far outweighs the "cool" factor of having a folding stock ... :wink:

It's not that much lighter if at all. I have nothing against folders, I just wish that ACE would make a better mechanism, the old style ones were tighter when folded but the new style has too much play, probably because it was redesigned so it could be deployed easier without pushing on it ...

ACE should just make an exact copy of the Galil type folder as that was the original inspiration for their stocks, they've made all their products compatable with each other, which is great but they should have just made an exact copy of the Galil's folding mechanism which is a much better design ...

The ACE stocks seem sturdy enough "as is" ...
I'm not sure about a using a Delrin or hollow tube in the design, I alway's replace my tubes with solid stock and use the longest screws possible, ACE uses two 10-32 screws which I wish were a 12-24. I also wish the stocks were steel instead of aluminum. Supposedly ACE stocks are in use in Iraq and Afghanistan but I wouldn't know ...
