Some guys just have a knack for thinking outside the box. Please take my money.

I am forever curious on which part rcmp wants to put the serial number on. Either way it will be a hell of a mess for them:

If serial goes on a single part, then we will just mass produce that part and register a bunch of ar15s.

If serial number goes on every part, then we will create a bunch of 6 pieces lowers, and trade and mix the pieces around. All of a sudden you have a bunch of people owning lower with 6 different serial numbers and rcmp can never track the rifle down to an individual.
 
I've seen a few different versions of these.
Blueprints are available online if you look around.

Not difficult to make for anyone with machining skills and a small benchtop mill.
 
I would imagine they might want it riveted or welded together, similar to how 1919 receiver boxes need to be 'permanently attached'.

We could do this now, with milspec lowers being in the $100 CAD price range it's not much of a hurdle to buy a dozen.
 
There is no logic to the AR's registration. GENERALLY, the part that holds the barrel is the registered part - except on the AR. For whatever reason, the default goes to the part with the serial number. So by convention where is the SN on an AR? I'd think the left or right sideplates would become the registered part, but who am I? Just a schmuck with a keyboard.

It would be trivial for them to call this a prohib item as there is no single piece that a Sn can be put on. No less mentally torturous for them than when they classified 80% receivers as prohib devices because you could make them into something that would accept an auto sear.

I'm thinking around $25/lower. Also I can't find $100 aero lower anywhere any more.

I actually spent the last 3 hrs online in search for the blue prints. Can't find them?

I believe this is one version of the design:

That's the biggest potential problem I see. If they choose to classify any part other than the side plate as lower receiver, then it would be capable of accepting side plates with auto sear hole drilled, thus making it a prohib.
 
If I’m not mistaken you would have to register it first with a serial number of some sort even prior to drilling the first hole in it, after that you could mill it out. Once finished the reciever would probably have to be verified by a gunsmith or the lab folks.

Right. Yes. You probably should do all that stuff.

The same guy that cast an AR-15 lower out of beer cans, cast an AR-10 version out of scrapped brass. The videos are still up on YewToob. The AR-10 lower looks amazing.

I'm more intrigued by the upper. Why does it have ejection ports on both sides? Can you flip the bolt and have a left ejecting version that easy? If so, that's very cool.
 
Is there any blueprints??

Scroll back up to post #12 of this thread.

It's a slightly different version than the one pictured.
But same end result.

There's a bunch of others around if you look.
