To make it lighter and cheaper, substituting the main structural parts of the body with polymer and just use aluminum in areas where high stress is observed would be a good idea, you'd just have to be sure to do it in such a way that the polymer wouldn't tear where it meets the aluminum.
That or you could simply reinforce the weaker areas with more polymer and alter the design to make said stress areas evenly dissipate the energy through adding structural buffers.
Then just make holes so you can simply screw in AR15 handguard rails, it'd be much cheaper than milling aluminum, and it'd be much easier and cheaper to repair if something breaks.
As for the magazine well, making it so that you don't depend directly on the metal structure of the rifle could open up more possibilities, such as using AR15 mags or maybe CZ mags.
To accomplish that, a good idea might be to make it so that the magadapter slides in like the old internal mag would, and have it locked in place with a cross pin, from there you could mess around with actual function as you please.
Otherwise just build this feature into the stock itself, but the first way could permit more customization at the cost of rigidity.
The main advantage to polymer would be the cheaper initial prototyping on your end, and then cheaper production costs in the long run.
As for the stock, you could make it even more customizable by making a sort of stock mount, which slides into some tabs at the rear. That way you could easily change out your stock platform, from AR15 style to whatever.
Honestly the main aspect you should probably focus on is the receiver area; make it the base platform for which the fore-end, rear, and handle can evolve from, that way you open up complete user customization.
For a gun as simple as the SKS, there is almost no reason not to give it that level of freedom. It's that customization aspect which makes the AR15 such a desired rifle.
Just go about it in such a way that you can use almost all aftermarket external parts for the most popular rifles.
As proprietary parts are a double edged sword in my opinion, sure it means you hone in all that specific business, but it also cuts you out from a much wider customer base.
I just had to look at your stock for a couple minutes to see that you could easily alter your current design into something even more useful, but that's the beauty of almost any initial design.
Good luck in any case 003, it's pretty good even at this stage.

I really like the newest look and using the actual AR grip and AK style mag in the drawing helps to visualize the end product.
I like the higher stock tube at the back ALOT. really evens out the whole look.
Just to clarify something Rallix was talking about, you cant simply "use" a different magazine in an SKS. An AR or AK mag wont fit into the magwell area and utilizing the stock to hold the mag in does not solve the problem. The mag must be mounted high enough that the rounds can be stripped by the bolt. The SKS has about 2 inches of metal where the mag slides in so if you used the stock to hold another mag, there would still be a 2 inch gap. Im not sure about a CZ858 mag. Never seen someone try that. But there really is no benefit to it as it would still only hold 5 rounds. The only real way to benefit from a mag swap is to use the XCR pistol mags and get the extra 5 rounds or the Beowulf mags so you can load even more. But the mods to the actual SKS receiver are not easily done and not at all easily done by the average guy.

i have an sks and i need a new stock.. the one i have loose. who ever had it before carved some of the wood off the front of the stock. so if u need a beta tester... u can send 1 this way

hmmm building is not my thing. lol.. but ill test the hell out of it
it my thing i'm a machinist , but my problem is i don't have the tool for the moment and no job , I'm planning to move in Edmonton soon

that's quite the issue, whats the tool? prob something expensive? would you be getting the tool when you moved?
need a cnc milling for a fast production , and that thing is expensive , but in the future i will have one , im moving to Alberta for making more money ,
when the drawing will be finished i will program it via Featurecam , with that i will know the time to make each part and the cost , for now i think the work can be done for probably 200$ to 350$ maybe less or more , aluminium is not a very expensive material and you can move fast in with the endmill

is that what your thinking the final price would be for the stock. or do you think your selling price would be higher?
for the moment i cannot give a number , depend on the production time , time i don't know , but it sure i will try to make some money , but i know 2 thing , if it cheap i will sell many of them , if it expensive i will not sell many
I'm aware of that, I don't think you understood what I wrote, because I addressed that gap.
There is benefit in terms of faster reloading using CZ858 mags.
Sure, using the stripper clip is hardly that much slower, however any convenience increasing device is a boon to the platform on the whole.
You're right though, there's a lot more benefit to the pistol mags and Beowulf mags, which is what I really have in mind any way, the CZ mag is just an added convenience for those who already have CZs.
My point here is that you don't actually need to alter the true receiver, there are plenty of ways to get around the issue.
Hopefully I'll be able to actually show you what I mean when my 3D printer arrives.

Definitely love that look!
actual look
Definitely love that look!
i think the first thing you need to do is get rid of all of the excess stuff over the barrel and gas tube and just focus on the receiver part to save weight.
If you look at it like an AR, you know the foregrip part around the barrel is often kept to a minimum.
