Don't know if anyone here was aware of this....a guy in the states is close-ish to releasing a 3d printed kit to convert a cyma m14 to a g43 looks likey.
No prices as yet, or a release date as he found the rear sight a little weak and balance too far back.

I'd give Vintage Airsoft a look up too. He made my G43 which is pretty good. Unfortunately I've had some mechanical problems with the gun which is no way the fault of Vintage Airsoft. Unfortunately I think I've bought a lemon of an M14

They can be hit and miss even with a known manufacturer. Mine caught fire the first time I used it!
As for the G43 kit, I'm not sure how it'd be with Plastics, my own conversion has a lot of parts that I'm going to have to replace with metal as they're just too thin and fragile to not snap off.
It looks G43 ish - apart from the magazine placement.
But raffles is spot on about the strength of 3d printed parts, especially the thing bits like the front sight hood and front sling mount.
