not for the moment , i have just finished to move in Alberta at Fort Saskatchewan this week , will look to find a job this week or at the beginning of the next week and after that it will be good to go , it will cost a good amount of money to make one , need to buy a new sks because i didn't take mine with me in the move , will have to buy , a stock , buffer tube , grip , some spring , roll pin , picatinny rail will probably cost near 150-200 for those parts , for the first prototype i may think a 400-500 easily , without a work i cant afford it for the moment , but be sure the day i have it in the hand i will announce it for the people who want to try it ,
 
added some funny stuff on it just for the look a Eotech and a m203

oh man... now I am going to have to actually take one of the SKS's I bought out of the box and clean off all the cosmo to actually use it to get it into this stock
 
i found a yugo sks cad file, it a little bit different than a Russian but it still not too bad for checking the overall thing that seem to be not too bad

here a pic

Yep you have a winner product right here ! Grat on the work.

I have done an SKS-AK in the past,did the stock in aluminum,and it was adding some weight.

I just hope it wont add too much weitgh on the sks.

i dont think i t will ad too much weight , it will just be better balanced and the thing is you can configure it like you want ,stock grip , iron , scope , all you want , i have many idea if this one work.

i know the sks is already front heavy it why i put many slot in the handguard , the weight depend more of the choice of the material

the weight depend too on what you will put on it too ^^

the centre gravity from the software is just behind the bold handle but not sure at 100% if it will be really there



like you say if it work it a winner it will be the most advanced sks like a ak12 for the ak platform
 
the other thing is how much to you want to pay for this , i will make the upper/lower , upper retaining locket , grip adapter , adding some spring and roll pin + bolt


you will have to buy the stock , buffer tube , grip , all the other thing ,

the total price will be probably 2-3x the price of the SKS
 
For the moment the drawing is finished , I'm measuring and quoting each piece for printing the drawing sheet and next stage after this .

yes i can be 3d printed this is one way that I look for the first prototype to be made , but not sure if the Abs will be enough strong and rigid , with the heat and shock ,
 
How exactly are the internal going to be attached to this stock?

How does it assemble/disassemble?

Does it just snug-fit?

How can you insure optics and such can hold zero in there?

Can we get some closeups of the parts like the main receiver area, magwell. grip area, etc.
 
you take your sks you disassemble it , you put it in , like a tapco stock , you want to clean it , push the green button to the rear , the upper will be unlocked now you have access to the dust cover , you want to remove it completely , take a punch and remove the roll pin who retain the upper and lower at the front end of the handguard ,

The quote for the internal come from my 1950 Tula ,

You are very skilled, it is a very nice project.
If you planing on manufacturing it for retail, the price is going
to be a huge factor.
Take for example the Archangel stock for the Mosin, it looks great, I want one,
but most of us, just can't justify the cost of it.

Keep up the good work.

ABS isn't your only option for 3D printing, Nylon is also available, it's more expensive though.

You can also reinforce printed parts with strips of carbon fiber around stress areas. The main problem will be insulating the plastic from the heat, especially around the chamber, but that can be easily over come.
Insulating the rails around the barrel could be easy as taking thin aluminum plates and attaching them around the inside of the rails spacing them periodically to efficiently absorb and dissipate heat from the barrel.

Another option would be to print it off in PLA and then cast it with aluminum, that'd be fundamentally cheaper than CNC.

Next year SLS printing patents will expire, so 3D printing with metal may become an option for you soon any way. Don't know if you want to wait or hinge your plans on that though.

Great work so far man.
