I am not making this thread to bash any companies.  This is NOT my gun.  I simply saw the photos on a gun group on facebook.

story goes "Buddy of mines Polymer Lower!! Pulled it out of gun cabinet by barrel and it slipped from his hand and dropped maybe 2ft onto a carpet floor.. "

no clue as to the validity of the story, but that thing obviously snapped lol

Yes, pretty dumb, but the bolt carrier group is missing.

Ha ha, I see the bolt group is missing, hard to fire when no firing pin

Although I agree that the rifle probably started out with a loaded magazine and off "safe", before being broken and they removed the bolt group. Really high speed, low drag type of operator there.

Thanks for sharing. Polymer has its place but it's not in the lower of an AR15 (GWACS lower is the exception IMO).

It could be an unloaded magazine.  I keep unloaded magazines in many of my guns so they don't get mixed up in my AR stuff.

Is keeping a loaded mag in a decocked rifle a Tactical Ninja Faux pas now?

This polymer lower only took 3 shots and it's done, kicked the bucket.

You can't put the weapon on SAFE if it's not charged/cocked.

I just dont get the market for the polymer lowers. An aluminum lower adds very little weight to the rifle, you can buy a stripped lower for $80 or less if you look around for a blemish, and an aluminum lower is certainly strong and durable enough for the application.

cheap and assembled  



But still, not that much cheaper than an assembled aluminum lower. I am a tightwad when it comes to money, and the few poly lowers I have handled have felt like a kids toy to me.

I was just given a ATI stripped lower for free and am putting it together for a light weight rig for the women shooters.

I won't trust it to HD use but everyone I have shot worked just as good as my aluminum ones.

Actually, on the polymer FCGs you usually can... looser tolerances let it happen.

Wow that ATI lower didn't take much abuse at all.  Oddly enough my New Frontier Armory Lowers are holding up fine and are sort of on beater guns.  Literally 1000s of rounds through them without fail.  not saying polymer is better, just that the New Frontier ones are doing OK.  I have many more Aluminum, and think Aluminum is superior, but the New Frontier is surprisingly OK.

I always look at this stuff, remember the line "you get what you pay for," and Chive on.

If the world fell into chaos, a lot of people would learn their cheap rifles and junk ammo (that some of them were so strongly advocating for everyone to use) would fail them.

Sure, some of the best brand rifles would fail or break parts, but in a much much lower percentage.

not true of the plum crazy lowers. not sure about NFA lowers but they use the same molds, however they recently changed the trigger group

Yep, that's the typical fail point for them.

I just got a new batch of NFA lowers in, and they will not go on safe with the hammer uncocked.

The early production NFA polymer lowers would, though.

I don't see what's "scary" about a condition 3 firearm (loaded mag inserted, safety off, nothing in the chamber) for either a shotgun or a rifle.  I consider condition 2 and 1 pistols a lot more dangerous and worrisome than having something as big and bulky as a rifle or shotgun "accidentally" chamber itself.

Saw polymer lowers for around $60-$70 at the gun show last Saturday  while DPMS lowers were $99.  I bought a couple of DPMS lowers.



Unless it's a reputable company I would not buy a polymer lower.  The brands I saw I had never heard of before.

NFA is going for under 50 bucks. I could break the two I have also if I swung at a tree with them.

I still am not entirely sold on the concept of polymer lower for AR rifles.
The SCAR may be the exception.

Ouch!  

Polymer lowers are cheaper, but that's not really the driver.  For me, the half pound weight savings is dramatic - and desirable.  If they all break like this upon being dropped, then that's not going to work.  I'm not clear yet if this is a fluke, or if these really are that tender.  I'd love it if there were a basic non-destructive stress test one could do to see if it's prone to breaking like this.

I did the same thing with a wooden AK Stock.. :(  It literally broke off, and it split into 3 pieces :(

lazyengineer...can you provide the specs showing that there is a half pound weight savings.  I have never seen specs showing that much weight difference.
