Don't waste your time and money. Get the real thing (aluminum alloy), they are cheap.

there are vids of adding alum powder to the mix .. ..

i was thinking more on the not having to mill out a 80% lower .. does the poly hold up .. ?

I meant a 100% finished receiver. Poly is garbage, trigger and hammer pin holes will enlarge and this will effect consistency of how the trigger feels. Plus other problems.

Get one and report back.

I always thought they should make the polymer lowers with oversized holes that are meant to have bushings pressed/epoxied in.

it wouldn't take anything special for someone to add that step, and the bushings wouldn't add much at all to the cost.

Maybe I would be proven wrong, but I would not trust my life with one.

I've seen torture vids of these they work but will break at the buffer tube eventually. New one seem to have a metal structure around the buffer tube .They will work for some time. Not a shoot everyday lower but I can see it fill a "liberator " gun type role if ever needed.

All this DIY stuff is becoming the rage. 3D printing, casting your own parts with polymer, etc. It all becomes landfill eventually. Have you folks seen something called a Gyr yet? It's where the Atlantic and Pacific oceans have some sort of swirl to them, and eventually all the garbage goes to those 2 spots. Each has like 100 million tons of garbage and at some point these 2 oceans will no longer be able to sustain marine life.

The holes in the bushings will need to be aligned to each other and the axis, which will be more complicated than just drilling through both walls. You end up with more costly receiver still of lesser quality.

The current mil.spec. receiver is different from the old mil.spec. receiver. They reinforced it in several places, which means there were problems. Even with aluminum alloy it is somewhat pushing the envelope, not something you want to weaken even further.

You just have a shaft in place through the bushings when you press/glue them in place.

Either that, or you use bushings with undersized holes and you drill them to size after installation.

Not sure if you could get away with molding the oversized holes for the bushings in, ATF would probably make you drill them, but you never know, since you couldn't install the FGC without the bushings.

Only thing I'd consider with this is for a dedicated 22LR upper. That's it.

Anything with more power I'd fear the BCG going through my cheek or neck.

If that was all that was available as a last ditch option for SHTF, go for it. Until then, don't waste your time or money.

Thanks for all the input .. I'm still looking into maybe doing a 80 lower .. I have a cheep drill press but the chuck is good and tight , just have to rig up a lock to lock it in place no depth locking of this thing .. got a machine vise so looking at XY tables .. ..
