Yup, I'm working on two big projects at once. Funny how I do nothing while I have a job and money but once I'm a poor student stuff gets done. :D

This is part 2 of my project, to read about the prototype concept proving Version 1, check out this link: http://www.canadiangunnutz.com/forum/showthread.php?t=76724


For version two I wanted to make a new "AK47 lower receiver" that was bent sheet metal like the real AK's. After some checking I noticed that the inside dimensions of an AK receiver are extremely close to the outside dimensions of an SKS. Since I want to build an AK copy, I had a company in the US that makes AK receiver blanks bend me up some metal.
THESE ARE NOT AK RECIEVERS! All they are is pieces of bent metal. They are too long, not shaped right, and lack the top rails to be used as AK receivers.

Bent metal

As you'll see, the SKS fits perfectly inside the bent metal. It's so perfect you'd think it was designed that way!

Receiver inside "AK blank". Note rear mounting post and excellent welds.

To locate all the holes I downloaded a number of AK receiver templates and spend a couple nights laying them out and comparing with the SKS. As the SKS bolt is longer, the mag well is located further forward than AK. I cut the template just behind the mag well and located. As you will notice, it would be impossible to use this as an AK receiver. Note all lettering that would identify template as being for a rifle blacked out to stop nosey people at the shop from getting on my case. :cool:

AK template chopped and glued to bent metal. Template is 1" shorter at the back to fit the rifle.

Today I got the "receiver" drilled and I just need to cut everything out with my Dremel. As luck would have it, i left my Dremel at my country home and don't have it in the city. :(

Drilled and ready for cutting. AK selector lever and hammer installed for s**ts and giggles.

Once the mag well and trigger holes are cut out I'll need to get final location of the "lower receiver" to the SKS receiver figured out. I may have to modify the hammer again. Material off the top and front will have to be removed. I'm most likely going to have some screws at the top portion of the "lower receiver" that screw right into the SKS receiver, as well as the two mounting points at the front and back bottoms.

I still need a new firing pin if any one has one.

Legal Disclaimer
For all you nervous nellies. Semi-automatic only AK47 trigger components are not controlled items. What I have built is not an AK47 receiver, it will not possibly function with any AK47 parts other than the trigger, hammer, and safety. This is not a firearm, this is a stock.

maybe you could use some thin wall structural tubing? Theres lots of metal choices out there and sizes with varying all thicknesses.

Interesting project.
 
so what are you gonna use for the top? Or are you just gonna overlap the two pieces and spot weld them?

Or I could use bent metal that is the perfect size.

But hey, doing it the hard way works too.

Dude! This is the second gun you want to transform into something else. Add that $300 and get an AR-15, put down an extra $150'ish for an SKS and get the "D" model!! :D
 
Ak...

Technically .... Yes and No...

There are Non-Restricted AKs..... He is creating a receiver that will use SKS & AK parts.

Very creative......

:)

Love it.

Look in the link on my first post to Version 1. The regular SKS receiver sits down in the "lower receiver" so it's basically just a stock.

No, I'm creating a stock that holds the SKS receiver. It just so happens to fit AK trigger parts and furniture. The SKS receiver remains mostly unchanged. If we start calling it a reciever then the classification issues may follow.

I assume your first comment pertains to my billet AR180B lower. First off, I don't want an AR15. I don't really care for the direct gas impingement operating system. I prefer a gas piston. If no one built new guns, the world would be pretty boring. As for my SKS, it is a D model, hence the reason I'm making it look like an AK.

As for "just buying" something, I'd much rather spend $800 building myself what I could buy for $400. I like to tinker and build, get over it.

Fair enough man. But you shouldn't lie about not wanting an AR-15. YOU DO WANT ONE, I saw your AR-108B. BTW, the gas system on AR's is "self-cleaning".... ;)

No, I don't. What I want is a gas piston rifle that has some of the features that I like about the AR15. The AR18 operating system is 100 times superior to the AR15.

I'd only every consider an AR15 if it was a gas piston upper.
 
You have to be careful with "out of battery firing" issues when mating SKS action and AK trigger group. Can you elaborate how you are going to overcome this problem?

No, because I haven't figured it out yet. :D


The HK M416 operates with a short stroke gas piston I believe and would probably suit your needs...
Sure, now just figure out how civilians can get them and you'll be a rich man.
 
so because your building a metal "shell" that holds the SKS reciever this makes the shell a stock?
 
Cool project..if you need any measurements/exact hole locations or pics,let me know.
I have one of the few legal russian made AK74 receivers in Canada

Yup, because the SKS already has a serial numbered reciever. What else would it be? The wooden thing you drop the reciever into that you hold onto is a stock. Why would this be any different? It's just a chunk of bent sheet metal with holes in it rather than a chunk of wood with holes in it.

its looking good sofar bryce

if you need any pics or exact holes...I won't help you..ok maybe I will

I got a norinco here I can use to help ya
Any ideas to keep it from fireing out of battery? How does the AK work in that respect?

I was thinking a linkage like the stock SKS trigger group, make it so the hammer can't drop unless it is pushed down, or something.

My other plan is to only pull the trigger once every second. :D
