Can only hope this is a new design with metal reinforcement, might have something then.

No metal reinforcement I can see
magnet sticks to nothing

observations from taking it apart
The FCG pins came out with ridiculous ease enough so it would concern me
The hammer and trigger fit in the receiver very tightly and ya had to tug pretty good to get um out after the pins were removed
The spot to screw on the pistol grip is poly also , so people better be care full with the allen wrench if they swap something out

still for the price I'm gonna buy 1-2 just for speculation purposes

here's a couple more pics

it really doesn't need metal reinforcement my poly lower works great.

All the reports of the failing plum crazy lowers don't seem to have any substantiation it a pic of a broken lower I can find more pics of busted aluminum lowers.

If the 3d printed lower doesn't convince you that polymer is a viable option especially when it's reinforced with other materials jsut like all the pistol frames out there then you should just quit the campaign against them.

I have yet to see an actual report of one of the new ones failing and i question the pics of the plum crazy.

go get one and show us it breaking under normal hard use or quit complaining about them


First of all, I never said polymer couldn't be a viable option. I think they are. Glocks and especially the M&P are reinforced by steel inserts.

Second, I bet you can find more busted aluminum uppers - they have been around the longest, most used, etc. Bound to break one some time. There are not many polymer lowers out there - YET. Third, how did the aluminum lowers break? Just doing a google image search for broken AR lowers revealed trigger guard ear breaks (still usable) and a couple polymer lower breaks of unusable form.

3D printing has shown to work but not shown to be durable - YET.

How many rounds through your polymer lower? What do you use it for or what action has it seen?

Again, I am not saying they are not viable just cautious of them. So are many other people too.

The receiver extension is metal on the lw 15, along with obviously the springs and buffer


^ See bold - meaning just the stripped lower.


A 3d printed lower as an option for what? I'm not one of these guys who abuse their rifles just so it looks used, but if you're going to compare the failure rate for polymer vs. precipitation hardened aluminum, you need to sort out those polymer lower owners who handle their rifles like a million dollar Strad.

I'd be more interested in a 3d printer making a fine-powdered, sintered metal part over anything plastic.

Well seems putting an upper on these is not quite a drop in deal
sold a few and this is what I have discovered with customers trying to put uppers of various makers on them

1 the threads for the buffer tube have a fair amount of flash that needs to be cut/sanded/beat down
2 the spot for the rear tang of the upper appears to be a bit narrow and again needs to be opened up a bit or the upper needs to be beaten into place with an alarming amount of force

Wasn't Omni Consumer Products the company that invented Robocop?

I have a polymer lower from Vulcan -put the torches down- that I have on a dedicated .22. I like these polymer lowers. You can put together a soda can killer really cheap, and I know 3 more people that wouldn't have had ar's that now have them because of the price point.
Honk if you've never seen an M203 fired out a car window.
