Yes , but only on a 22LR build where it's just fine.

I have the newer ATI polymer lower with the metal inserts and it works fine and is plenty tough enough for normal use. I would still trust aluminum more if I was going to throw it off a roof or beat down a door with my stock. With the steel inserts it may be just as durable as aluminum but I still have my doubts.
I would avoid polymer lowers unless they are reinforced with steel in stress areas, especially the receiver extension area. I paid $35 out the door for mine at Rural king but it's not an 80%. |

With forged aluminum as cheap as they currently are, I see no need.
I've not seen a poly lower other than the GWACS that can take the abuse that a forged lower can. Even the GWACS have drawbacks. |

If you just want a plastic 80% lower to practice w/ before you start making aluminum chips, EP Armory is half the price you're quoting, OP.

You can get an aluminum 80% lower for $30-$40. Why even consider a $60 inferior polymer lower?

The $60 Polymer80 kit includes the jig and the milling bits. The $30-$40 aluminum lower does not, so there would be the additional $100-$200 for a jig and bits. Quote HistoryQuoted:

Can't be that great of a jig and same goes for the bits if they're included with the lower for only $60. Hell, a quality drill bit by itself will run you $10. I have a 5D jig with their tool kit and it is f**king awesome. I would go with an aluminum lower every time. |

I want to get the aluminum 80% kit from either 5d or 80% arms but getting started is $300 as I dont have a router yet. My co worker used a dremel on his glock lower and it came out beautifully but wasn't sold on the polymer ar lower pistols are one thing rifles are another story

Run away from any and all polymer AR-15 lowers that aren't CavArms.
