You should like Glock, I do and have three. Also three 1911s. Fine pistols. But I won't have a plum crazy on my ARs.

What was the issue with plum crazy? And could that have perhaps been remedied in a new method by NFA?

IIRC, there was a factory in Lake Havasu City, AZ around 2000 or so that made polymer lowers and complete ARs. Seems like their name was Professional Ordinance or something like that. They put out the Carbon-15 which soon acquired a bad reputation and they got in trouble finiancially. Around 2003 Bushmaster bought them, taking over the LHC plant and selling a new and improved Carbon-15. It soon after also got a lot of complaints but at least BM got rid of P.O's proprietary barrel and bolt. A couple years ago BM closed the LHC plant and moved C-15 manufacturing to their Windham, ME factory. Of course last year they shut that down and moved again to Ilion, NY. BM still sells the C-15 which may work now or may not. It seems hit or miss depending on who you talk to. So many questions...

A few years ago we hear of a company PlumCrazy which starts selling polymer lowers out of Lake Havasu City of all places. Hmmm??? What I remember about them initially was there were a bunch of rave reviews in all the gun rags (I remember an especially shameless shill review in Shotgun News a couple years ago). Then of course reports from folks who couldn't pass up a lower with LPK for $100+. Then what was really eyeopening was over time most of these folks quit bragging on their PlumCrazy and you'd even hear complaints here and there. Then they tried to change their name to PCF but soon after the company went bankrupt. Or did they? So many questions...

Then New Frontier/NFA of Las Vegas comes along and guess what - they're using the old PlumCrazy Lake Havasu City plant. They tout a Gen II model but who knows. Are they PlumCrazy rising like a Phoenix out of the ashes in the Arizona desert? So many questions...

There was really good company out of AZ called Cavalry Arms that sold an integrated lower/A1 stock. From all reports these things are strong but of course many folks want a collapsible stock. Cav Arms also went bankrupt but it was due to FFL violations not bad products. I understand a new company is selling the old Cav Arms lower now and it's quite good.

Bottom line, I think in normal times it's better to buy a milspec 7075-T6 lower and go from there. Right now times aren't normal so if desperate for a lower, maybe NFA is worth a try. And it seems to be an ideal lower for a .22lr upper. Otherwise, so many questions... That sums it up for me.

Have nothing bad to say about glock, i just don't like the long trigger pull or the way they fit my hand. Thousands of LEO and years of use don't lie. Good gun is is a good gun.
I am just a cocked and locked kinda guy.

Heard that. I do love to carry cocked and locked.

Ok guys thanks for all of your ideas and opinions on the matter . I think it was good debate thread on polys. I put in a bid for a FMK composite lower at gun brokers and won it for 110 bucks .Its a good looking lower clean and smooth surface . With that said I will be giving a field repot as soon as I can fine A bcg and lower parts kit to finish this build . Thanks for everyone's input

I'm waiting on a Spikes upper to arrive tomorrow via fedex. I'ma slap it on a NFA poly lower and see how it all performs as a unit. I'll let you know how well that goes.

Here's your range report, straight from the horses mouth. Thousands of rounds many years of abuse, and still rock solid. Congrats on your poly build, I assure you , you will be glad you bought it. I can hear it now " Damn, they were right, these things are great, wish I'da bought one years ago."

Maybe I should get another....

its a known weak point in the m16 platform. this comes straight from military design specs since single biggest difference between the A1 and A2 in the lower reciever itself is a reinforced lower reciever extension. even aluminum recievers break right at that point. most rifles in the hands of your typical civilian user doesnt put much stress or high round counts and almost none get shot enough to wear a barrel out.

it doesnt mean a poly reciever is going to shatter into dust just picking one up, it means its got a greater chance of failing at that point than an aluminum one. im not interested in making my firearms more delicate

when you run a gun hard in a ohsht type environment or train for ohsht your going to be hitting the deck hard often landing on your weapon. using it for a club in some cases etc.

just riding around in the back of your truck plinking with a poly reciever doesnt really stress a gun much.

you can do what ya want im not invested in what you carry or like as a firearm but you wont ever never see me replacing a solid aluminum lower for a cheap poly plastic one to shave a ounce of fat off the gun. ar15 are already delicate guns that dont take to being abused well. i see no sense in making them weaker than they are.
