Only using a CMMG .22 upper but it shows promise.

A .22 upper doesn't use the buffer system and that's where the failures usually are: receiver extension snaps off.


"3d printing" with titanium etc is a far cry from the do it yourself at home machines, ie, a couple of orders of magnitude of cost

Ti is a pretty dumb material choice for a lower too since Aluminium works 100% fine at a much lower price point etc

Yeah from what I have read the have got it to the point where they can put 100-200 rounds before it self destructs.

But if you can do it for cheap, why the hell not i suppose.

I imagine it would just be cheaper to buy a Alu lower than 3D print a Ti one.

Be a good thing when this new type of self healing, super tough plastic IBM just invented turns up on the market

Because actual good quality milspec aluminium lowers are $79.10 from Brownells and will last around 1 million times longer

So true but remember the lower is the only part that is a registered part with a serial number, by printing you are by passing all official checks. All other parts of an AR a 10 year old could bye over the internet. Print him self a lower and he's got one mean killing machine. If I was 10 I would print one off...if I had a printer.

Wanna try to at least appear somewhat socially acceptable?

Fortunately it would be rubbish and break after a handful of rounds!

An A cat lower is also "unregistered"...

Like all new products, things improve over time.
Even an A-Cat lower you still need a firearms licence to purchase.

Yeah but currently they're shit


And of course you do, which is a good thing

Indeed, I meant that as a do it because you can, and its interesting, rather than a do it because its the best idea. Besides when it breaks you can just get a quality aluminium lower from brownells for $79.10
