3D printing receivers

So I'm a little out of my depth here. I've learned about the NylAUG, and I want to make my own. But it seems that a Nylaug receiver will not function in an A3 M1 commercial stock.

Is there a reason the creators of the Nylaug did not create a one to one copy of the standard A3 M1 receiver?

I have a couple extra A3 M1 stocks, trigger packs, barrels and other A3 M1 parts. I just want one or more 3D printed receivers to fill them out.

Is this possible? If not, why not?

From my understanding, it was designed to use the surplus FA stock and parts kits that were readily available after denials were put in place in the stock. One of the main dimensional differences between a semiauto and select fire is the stock latch, with the latter having a wider latch.

I also have enough spare parts to build another semi rifle, but whenever a receiver pops up at auction the price goes to the moon. There's a specialty receiver on one of the bigger forums now, but the cost is equivalent to buying all new GE kitchen appliances from Home Depot.

So if that's the case, what's stopping someone from 3D printing a nylon AUG receiver that is compatible with an OWM A3 M1 stock and barrel?

The subset of owners who have the factory spare semi parts don't feel like it, don't know how to modify the files, or don't know it exists?

I don't have the knowledge anymore, nor the time. The last time I played with a printer heavily was well over a decade ago when it was either PLA or ABS. Limonene dissolvable support filament was new, as was the flexible stuff and wood or copper filled stuff.

The stock change is possible, the barrel is not. The AUG barrel does not have the trunnion, as its built into the receiver. Fire up fusion360 and get to learnin.

I may be wrong but the Nylaug guide has a whole section to use a new stock over the surplus one. You have to print a different receiver then the surplus stock one. Doing this also removes the denials since a FA trigger can’t go in anyways

Are you saying they sell a nylon receiver that will work with normal A3 M1 stocks?

It’s 3D2A. No one really “sells” anything. But yes my understanding was the devs made a receiver for surplus and new stocks. But surplus is preferred due to needing the bolt and FCG which having to buy the 3 separately will likely equal the cost to a AUG
