maybe receiver be a bit longer in back yes?

Looks like the charging handle is interferring with the sight.
Otherwise, i'm not competent to refute or validate this design.

Val mechanics in 7.62x39? Don't see much point.

Charging handle is interfering with sight

As for anything else, I would say, ejecting a mag looks painful, and fuck that charging handle as a whole.

No, in no way could a magazine store that much ammo like that. The follower and spring take up space too, they don't just magically fuse together when compressed.

Went through with some design changes

Recoil spring is probably too small and should probably have a continuous guide considering the offset from the bore

Alright follower spring is better accommodated now

Gonna need a more detailed assembly drawing on that trigger group fampai.

Essentially on full auto only the rightmost finger (trigger sear) interfaces with the trigger, on semi the leftmost finger (disconnector) interfaces aswell, which catches the hammer when it would otherwise be released by the trigger sear, on safe the inverted L shape pretty much prevents the hammer from releasing and locks the trigger sear in place

Where is the spring in the mag?

Ok, a few things:
What is the target market for this?
If you're going for a US domestic production rifle, you'll need a much longer barrel.
If you want to go military, you'll need to explain why they should adopt this over (and spend the money to switch from) a standard AK or AR pattern system.

Also, the gas port looks to be way to close to the chamber. That will lead to stupid high pressures in the gas system (and the rough recoil that comes with it) plus lead to premature erosion of the gas port.

>What is the target market for this?
Excusing the poorly represented mag, it's supposed to be pretty much a modernized 7.62 carbine. Similar market to the Galil ACE, except it's more slick
>If you're going for a US domestic production rifle, you'll need a much longer barrel.
Different barrel lengths could be used to avoid NFA regulation, in this configuration it's a military rifle
>If you want to go military, you'll need to explain why they should adopt this over (and spend the money to switch from) a standard AK or AR pattern system.
I guess that's a problem not limited to just weapons someone like me would think up on their own time as a thought experiment, but I'm guessing if you made it out of extruded aluminium and polymer it would be really durable and cheap to manufacture, which would be enticing to military contracts
>Also, the gas port looks to be way to close to the chamber. That will lead to stupid high pressures in the gas system (and the rough recoil that comes with it) plus lead to premature erosion of the gas port.
This came up earlier and I moved the gas block forwards by not a very significant amount, but there is also a gas setting knob and there are gas bleed holes in the gas sleeve that is connected to the BCG.

>modernized 7.62 carbine
for what reason?

AKM's are getting old, some countries have stuck to 7.62x39 and there are few modern options for that

>What is the target market for this?

pretty sure it's someone's hobby project, you tryhard dumbass

Have you worked out an intended method of manufacture for the various parts? Materials, starting points, etc? All steel? Aluminum extrusions? Forgings? Polymer castings?

Furniture is polymer, dust cover and receiver would be extruded aluminium, bolt would be 8620 steel. I'd probably make a mechanical CAD model if I was 100% serious about making this thing

Noice

With that long of a barrel and that short of a gas system you are going to over-gas the shit out of that rifle.

This is something I am acutely aware of, which is I made an alternative version with a much shorter dwell time

Pretty neat, OP. Where’s the mag catch?

I guess it isn't articulated well in the drawing but it's similar to the AK mag catch except you push a button like on an AR and the tooth interfacing with the back of the mag slides out of the way horizontally so you can just pivot the magazine out

Looks better user. I would also say that yes, making an AK type rifle with an AR-18 type bolt carrier is really cool. However, the reason the AR -15 is so popular is simply due to the systems modularity. Rifles with that type of receiver (I am assuming your receiver would be stamped steel.) is no easy to do work on in terms of modularity or serviceability. You might already be aware of it, but look into the Daewoo K2. Kinda does everything you are already currently trying to do, but with the modularity of an AR.

Isn't this basically what the cmmg mutant is?

I was thinking of an extruded aluminium receiver like the Bren 805, the SCAR and a few others. I imagine having MLOK slots in the handguard and a pic-rail attached to the top with weavering ironsights is a good modicum of modularity, also with a side-folding adjustable stock. I see what you're saying though, nothing can really compete with the AR platform

>extruded aluminium receiver

RIP to your budget. The SCAR hasn't really been adopted by anyone on a major sacle user due to the sheer cost it takes to produce one. I fear the the Bren is going to suffer the same fate.

>sacle
scale*

I wonder why stamped receivers fell out of style.

Try designing a polymer receiver.

Literally this.

There's literally nothing more modular or easier to service about a stamped receiver compared to machined or extruded ones. I believe it comes down to cost, extruded aluminum is very cheap and you don't need huge presses and molds for it.

>The SCAR hasn't really been adopted by anyone on a major sacle user due to the sheer cost it takes to produce one.
But that's actual bullshit. The setup cost is high (though the same is true of stamping and milling, so its ultimately inconsequential) but the individual cost per unit to produce a SCAR is lower than an FN M4. That was literally one of the stipulations of the design brief. The reason it hasn't seen mass adoption is due to nebulous benefits over competitors with a wider range of vendors and support.
