Ever hear of the Freedom-15?

[BISHOP]

Its a 100% Polymer AR15 receiver that you POUR yourself.
The vids are simple.
Assemble the mould. Mix the parts and pour. Wait an hour and then disassemble the mould and then bake in an oven for 2 hours.
Every pin is there, and the buffer tube hole as well as the pistol grip hole is already threaded.
Its reusable, they give you color dyes to color your receiver and you could possibly make and have ready for assembly 5 in a few hours

Here is a un-moulding vid.

Since we're all curious

2 points.

1. They had bubbles in the receivers, instead of pouring it in, maybe more forceful injection. Also maybe pre warming the mold and polymer then keeping it warm while it sets.

2. You could easily lay in an aluminum sub frame for the stress points, then pour the polymer around it, encasing it.

I think this is a great idea, but it needs a few more evolutions before it's ready.

In the Link I posted in the second version video they say to warm the mixture for no more than five minutes for best results.

If it is thermal curing warming it could cause premature hardening before you finish a pour. I'm wondering if powdered aluminum or steel could be incorporated into it to add rigidity? Brownell's sells powered metals to put into their epoxy bedding comoupnds called Accraglass. It definitely makes the epoxy a lot harder.

I wonder if it is a hard Urathane. I know that a "Castable" Urathane has been around for a long time to make prototypes in the molding world.

The mixing and pouring video explains everything.
They mention only to heat the separate components in warm water for a max of 5 min. Not heating the mixture.
And pouring very slowly to avoid bubbles.
