If you stripped the metal parts does a magnet stick to it anywhere? Or set off a metal detector?
Can only hope this is a new design with metal reinforcement, might have something then.
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.
