7.62x39 bullpup

Postby John A. » Mon Jun 16, 2014 2:04 pm

Several years ago, I came across a bullpup stock for the SKS that I actually liked. I had seen several others that I cannot say the same for. Matter of fact, I will go so far as saying I didn't like any of the other designs whatsoever.

So, I decided to be patient and see what some of the reviews were like before spending that much coin on a stock kit.

After getting interested in it again, I saw a grand total of 1 negative review and countless positives.

So, I decided to go ahead and order one.

I wasn't really excited about the price ($250) considering that's about what I gave for the gun itself, but having wanted a bullpup style gun for a while (like the IMI Tar-21), seeing how it changes the traditional sks entirely, I looked at it like I was just buying a different gun. And a lot less expensive than the tavor and there is a lot to be said for the x39 round anyway.

The stock is supposed to be here tomorrow (though the fedex tracking info seems a little wonky at the moment), I have prepped the gun and removed the front sight base/bayonet lug, the stock, the handguard, and the rear leaf sight over the weekend just to save myself some time tearing it down.

I have a couple different flip up sights that I can check to see which I like the best on it, and have an old N cell holosight currently collecting dust that I can throw on there as well since it's going to be so compact, I figured that it would make for a quick swinger in that style of setup. I also am going to try a magpul front grip on there to see how it feels too.

One issue with these old guns is I had already swapped several parts for 922 compliance so I am good there.

gas piston (1),mags (3), removing the foreign handguard altogether should also take the foreign part count down as well since there will not be a foreign part on it there (-1), and the stock itself is also made in the U.S (1), so that will be more than enough parts to comply with that stupid law.

I also added a murray firing pin to the gun as an added safety precaution that is also made in the US, though it doesn't count as a 922 part.

My biggest concern for the project was one that I didn't even have to do, but since I have no real reason not to thread the barrel for a muzzle attachment and to make it as compact as possible (and still be over the minimum overall length and barrel length as to not be an SBR) I cut the barrel to 17 3/4 inches, crowned, and threaded it for combloc standard 14-1 left hand thread and used a US made A2 style flash hider which should take the part count down by another point now just because I could and I am happy with the way that turned out.

This is actually kinda neat - I was considering getting this setup as I have my 03 C&R now, and can pick an SKS up pretty reasonably priced. Was it limited to specific manufacturers? (Yugo vs. Chicom?)

No it's not limited to any specific origin country, though with some models I think the grenade launcher front sight have to be removed in addition.

If you check out their website, you can see several different config's in their feedback section

see if these are more what you're looking for





I was able to fit everything together this evening. Took considerably longer than I expected, but everything is solid.

It handles really well. Much better than I anticipated.

Fast to point, quick on target. When it's shouldered, the weight distribution is a dream. It could even be aimed and fired with one hand behind your back.

Some specs:

Overall Length: 29 1/8"

Barrel length (including flash hider): 19 1/4"

Weight: 9.8 lbs -- includes sling hardware, flip up sights , optic and empty mag

very nice looking unit
How did the conversion affect the trigger weight & feel?

Rattler, I like the idea of having a compact weapon with a lot of backbone. The sks bullpup would certainly fill that role.

The trigger pull is not real bad.

There is a screw in/out adjustment to help you shorten the takeup out of it. And the new trigger has a cam action that contacts the rear of the trigger near the disconnect. Just from describing it, would be confusing, but if you watch the 2nd assembly video, it will become more clear of how the bullpup trigger works.

The more I look at this the more I am grooving on the idea. . . +1 on the "I need an SKS now" list. . .

So I looked at the sgworks.com website - but they don't have much in the way of descriptions. Does it use SKS magazines or does it use AK style mags with the conversion..?

Mine uses SKS mags.

Only the SKS-M and SKS-D accept AK mags by default.

I am unsure if the stocks work with the SKS-M or SKS-D variants, though I assume they would, only would have a larger opening in front of the mag, but I think anyone who has an M or D variant should contact them and find out for sure because I have been wrong assuming before.

From the opening page of their website:

http://sgworks.com/ wrote:
>>> Compatible with AK and Tapco 20 round detachable magazines


And on their store page:

http://sgworks.com/ wrote:(If you have an SKS Model D or M that takes detachable AK Mags you will not need our Extended Mag Release.)


It's got me itching for an SKS, I need to grab one while they are still affordable. . . As soon as I can afford to that is! :lol:

OEM 10 round fixed

SKS 20 and 30 round detachable magazines

AK magazines (if your SKS in its present form is compatible with AK magazines)

Yes, it does, if your SKS does accept AK mags then the stock will work with it.

^ This

Some SKS stocks were designed to accept AK mags. Those are the D and M variants. Every other SKS only takes SKS mags.

But the stock won't convert it from SKS mags to AK mags.

The receiver has to accept AK mags to accept AK mags. Has nothing to do with the stock, but the stock works with both types of receivers.

Hope that helps answer your question.

Ok so I know many countries made these guns over the years but does anyone know what countries and years made the (D and M models)? I am looking for the fastest way to find a correct host rifle to start with. The info I have found does not talk about D or M models? Thank you for your input! 8)
