Any thoughts on a polymer lower.
Found this using the search function, I have no personal experience:
Stop by the Introduction section and check in.
Some people swear by them. Others curse them.
Personally not a fan.
Why not? Have fired one. I have watched a lot of youtube videos of people that both liked and disliked them. Seemed many were pleased with them.
The ar15 lower isnt a good design for poly lowers. Too many stress points with too thin walls. The thicknesses on the sidewalls extension areas etc were designed with aluminum in mind and the stress factors aluminum is capable of withstanding. Poly needs to be much thicker in some areas to be rugged enough for my tastes.
Poly lowers will work just fine in light range use. If allyour ever going to do is plink at paper its general ok.
Glad you said it. I kinda got tired of saying it all the time.
Yeah it would be handy keeping a database of routine answers to copy&paste for frequently asked questions. Or maybe a sticky of FAQs.
For a light use plinker that you intend to be either really cheap or extremely light, they're just fine. And I'd go with the NFA over most other poly options.
I've built on a couple poly lowers, and then immediately sold them. That should tell you something. I do believe these are functional lowers that will generally perform admirably. I wouldn't build a rifle I intended to run 20K+ rounds through, or even one I deemed a personal 'keeper' around a poly lower. It screams 'cheap!'.
So because I typically build with quality parts (mostly BCM, some PSA), a poly lower will only do a disservice to my rifle's rep and resale value. In that regard, they'll probably never be for me. But it's not a bad idea to keep one around, if only to build an ultralight fun gun on one. Just don't go crazy trying to build a $1500 gun on plastic chassis.
It is becoming increasing hard to get lowers. The deadline to legal purchase one in my state is approaching. I can get one of these lowers shipped complete. Then continue to look for a better lower.
Or you could move. I would suggest that.
If you can't find anything locally then go on gunbroker.com and you can find decent brand name complete aluminum forged lowers for less than or around $300 worst case scenario. It beats buying a poly for short term use.
Wish it was that easy. I would move to Texas.
So I got a NFA complete lower for 100 and a spikes stripped lower for 125.
You need both.
My plan is to put an upper in the NFA right away and take my time with the spikes.
I have sold a lot of the NFA lowers, never had a single complaint. One of the reasons for that, though, is that I try and give my customers the real pros and cons of both types. As was already mentioned, if someone is going to do competition or just shoot alot, I usually recommend an aluminum. If it is completely about how much can I build an AR for then I suggest the NFA. They are by far the best poly on the market as far as I am concerned. Forged aluminums are co,img down in price evey day now. Heck New Frontier has started making them as well. They also started making their own billets. I got 5 of the initial run of them and they were as good as any of the billets out there, just cheaper.
