Saiga 12/Bulgarian folding stock conversion

[MINI SSS 0]

I just purchased an Arsenal SLR 106F (basically an American assembled Bulgarian AK74 in .223 with great assembly quality and cheap paint finish). The folding stock setup is the best in my opinion. The black plastic folding stock is rock solid in either position. My Saiga12 19" threaded shotgun will be here next week. What parts exchange and receiver modifications are needed to mount this same Bulgarian folding stock and side locking piece? I've checked the regular posts and tech posts, but I haven't seen this modification on a Saiga12. Basically do have to weld a Tromix type receiver plate to the receiver, or is their a no weld option?

Ace makes a bolt-in receiver block that basically does what our weld-in plate does, if you need to avoid welding.

I did all the trunnion work required for the bulgy polymer side folder:

 

http://forum.saiga-12.com/index.php?showtopic=31499

 

Same trunnion just different stock. Couldnt find a poly in stock so just using the triangle folder.

 

Did the same work but with the actual polymer stock on my IZ-132 as well.

 

Trunnion work to use the Rusky side folders on an S12:

1. demill the origional rear trunnion without damaging the receiver
   
2. drill the two extra lower holes
   
3. cut the holes for the latch/button(lots of little filing)
   
4. get the folder trunnion and rivets(rivet that goes through the trunnion, receiver, and optic plate is not standard & is not included in any kit)
   
5. match up the new trunnion with the original trunnion. A small amount of the new trunnion needs to be filed down. Skotts thread(linked below) illustrates what needs to be filed
   
6. (optional)refinish the new trunnion
   
7. rivet the new trunnion
   

 

Skotts conversion has more details on the holes that need to be cut for the front latch:

He bought the latch from the russian military page though. Thats like $100+. I made one instead bc Im stingy

If you use the stock one you'll have to modify the stock a little. Shown on the last page of Skott's thread.

Thanks Bob and James. The information couldn't have been more exacting. John

There are also a couple of good Saiga 12C conversion threads over on theakforum.net,

 

....one by Tomovich.....

 

http://www.theakforum.net/phpBB2/viewtopic.php?t=4575

 

......and one by and one by vz58....

 

http://www.theakforum.net/phpBB2/viewtopic.php?t=76938

 

.....which have some some really good pictures of the Saiga 12C front retaining latch (made from scratch in Tomovich's thread, and a picture of the factory latch in vz58's thread).

 

In vz58's thread sKott also posted some large detailed pictures of the Saiga 12 handguard he modified (the modifications being necessary so the handguard could accomodate the front retaining latch spring and the latch-pin retaining clip installed in the front of the Saiga 12 receiver), and pictures of the front of the receiver with the handguard removed which show pretty good detail of the front latch installation.

 

If the links don't work for you, just go to the 'VEPR/SAIGA' section and do a topic title search for "Saiga 12"C/K" folding stock conversion parts, etc." and "Saiga 12 conversion progress" .

Is the Izhmash folding stock with Saiga trunion available or is another type usable like those for the Krinkov on the KVAR site? John

Factory Izhmash Saiga 12C rear trunnions are virtually impossible to find, but fortunately any standard AK sidefolding stock trunnion, either russian or bulgarian (like the ones K-Var sells), will work with some minor modification (by the way, the short-barreled Krinkov type AKs use the same rear trunnion and front latch mechanisms as the standard rifle type AKs). The main modification is that some metal must be removed from the top front part of the trunnion, so the Saiga 12 bolt carrier (which is bigger than a rifle type AK bolt carrier) doesn't hit it when it comes back. See post 53 on the second page of sKott's conversion thread ( http://forum.saiga-12.com/index.php?showtopic=21197 ) for details on where and how much metal must be removed.

 

Also I believe sKott mentioned that he had filed out a little shallow pocket in the front of the rear trunnion to make a space for the back part of the firing pin, so it wouldn't hit the front of the rear trunnion when the bolt carrier came back.

 

One final thing, on AK type rifles with the side folding stock I believe the rear trunnion is installed at an angle of 6 degrees, while on the Saiga 12C it is intalled at 4 degrees.

These are all Izhmash parts:

http://www.rusmilitary.com/html/c-deact_furniture.htm

 

You pay a heafty premium though.

 

 

This is the bulgy kit I used on my IZ-132 and this will work on the IZ-109

http://www.k-var.com/shop/product.php?productid=16849

 

Obviously those are out of stock.

 

I got a hacked up receiver kit off of gunbroker that had the front latch(works with rifle only that I didnt use), rear trunnion and rear latch, and triangle folder. All parts were still riveted to hacked off chunks of a receiver. So I had to demill the new/used trunnion.

I don't see any more of those kits on gunbroker but I'd recommend any that this guy sold:

http://v4.beta.gunbroker.com/Auction/ViewI...?Item=112032757

 

Every now and then parts will show up on the ar15.com equipment exchange forum.

 

edit----

If you want to go this route you will probably have to wait awhile for all the parts. Everyones buying everything imaginable right now. Ontop of these parts being scarce during normal times.

I never liked any of the ace stocks. So for me I'd wait.

Gives you time to cut the receiver, weld up the old holes, and refinish the receiver. If you're doing this all by yourself and dont have much experience like me that can take some time anyway.

I was going to go that route as well, but K-VAR sold out of folders and it doesnt seem like there coming back:(
