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

the more scary part is it's in semi and a mag is in it........... 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. |

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

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.

I just dont get the market for the polymer lowers. 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. |

| 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. |

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. |

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. |

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.  http://www.thetruthaboutguns.com/2012/12/chris-dumm/gun-review-new-frontier-armory-lw-15-polymer-ar-lower-receiver/ Middle of article. I can feel it first hand as well - distinctly lighter, and different balance as well. |
