I’d give it a go… I may give it a go actually.
Plastic is fundamentally neither inferior nor superior to metal. What is inferior or superior is the design. A design made with polymer in mind will perform superbly. If they’ve done their engineering homework and have experienced designers, I’m sure it will be good.
as far as durability goes, durable against what? sand? shock? saltwater? Metal has it’s place, and so does polymer.

Komrad, it’s a high impact polymer like anything Magpul would make, or like an LMT stock.

Jason,
I have no experience with PlumCrazy. However the people that made these lowers are the same people from Professional Ordinance. Professional Ordinance plastic lowers are known to break in half.
It is not a good idea to mate metal and plastic threads together. BTW the PlumCrazy trigger group are made out of plastic.
Arfcom have a one year old active thread on PlumCrazy. 16 pages and counting.

The only AR15 plastic lower that are proven to work was made by Cav Arms. Cav Arms got busted by the ATF and gone out of business. They made it work because their lower is one piece (lower and stock are together) and some area were reinforce with extra plastic.
I bought two Cav Arms, one for my cousin and one for me at $89 from DSG Arms. Be advise there is no more warranty on these and the only reason I bought it was for my AR15 collection. However I wouldn’t mind getting the purple, blue, and yellow if the price was reduce to $89. Use these lowers to get kids into shooting.

Field test with .450 Bushmaster upper.
Or a Bohica .50BMG upper.
In extreme heat or cold.
Then, maybe.

So is it cheap ‘plastic’ or quality ‘polymer’ like glass-filled-nylon. I can’t tell because people who don’t like polymer always refer to it as plastic, which is technically correct but demeaning.

Jd,un1911: I have had one if these lowers since June and can’t find a bad thing about it. I’ve shot hundreds of round through it with a bushmaster upper. Also you are mistaken, they are not the same people as the professional ordenance. And Calvary arms good quality??? Have do you really own one because you really need to check out the forums and what people say about them. I know the owner and have talked e with him quite a bit. Also people do not realize that price is for the COMPLETE lower; included are the lower parts and the complete collapsible buttstock.

You’ll have to forgive me if some of my post did not make sense. I’m on a Droid and I can’t. See some of the lines I’m typing. Also I was reffering to Thea owner of PC, Ed, he’s a great guy and wanted to make a way for pretty much every patriotic American to be able to afford a AR-15. check out his youtube channel. “plumcrazyfirearms” he’s got plenty of bids of him and his friends using his product in semi and full auto.

Also i think jdun1911 was kinda right on one thing the guys at plum Crazy was involved with the Professional Ordinance and then started Plum Crazy or something like that there was some kinda tie at one time. And there was some fitting problems with the Calvary Arms lower with I guess you can say the first gen but then I think they got all that straighten out with the second gen. I will let you know when I install mine I am using it for another build.

I have 2 of the Plum Crazy lowers. I have replaced the trigger groups on both lowers. I have found a major issue with the polymer trigger group that, in my opinion, is not only a safety issue, but a legal issue. On one of my lowers, with the hammer forward, the safety on, the charging handle was pulled to chamber a round. Part of the hammer started to get rounded over to the point that if the trigger was not quickly released after firing a round it would drop again, sometimes cause not only a second, but third of forth round to be fired. I have a new upper assembly chambered in 450 Bushmaster on the way and plan to mount it to one of the lowers.

I have three Plum Crazy lowers and love them. One is on a 5.56, one on a 6.8 and another on a Bushmaster 450 upper. Now the Bushmaster you can feel the recoil like hell but the lower stands up to it. The 5.56 probably has around 400 rounds through it with out a glitch. There is also somebody on the web that did a beuwulf build on one with no problems. I recently bought a used Calvary Arms lower but have not mounted it on anything. But I recommend the Plum Crazy lowers for the price you cant beat them.

@Jason
Thank you for the clarification.
I wish people would stop saying plastic when referring to high-impact glass filled nylon polymers.
To “plastic” skeptics, metal may be more scratch resistant and better suited for handling high pressures but, polymer doesn’t rust, is impact resistant, is less expensive in some cases, absorbs recoil better in some cases, and can be shaped into different though not necessarily better shapes.

These things have been the talk of the town over at AR15.com, and most customers seem pretty happy with them. The general consensus is they’re great on dedicated .22s and fine for a range gun, but no one will trust them in any serious role until someone can torture test a few.
Interesting to note the fire control parts are all plastic too, but some users have reported swapping to metal internals works fine and doesn’t seem to wear the pin holes excessively.

No thanks I will stick with an all metal AR. I own a number of polymer handguns but plastic is plastic and in the end they all are not as durable as metal.

I would not recommend buying it unless you’re stripping it for parts. The receiver is plastic and the plastic threads is not strong and durable enough to hold onto the aluminum extension/buffer tube. In other words sooner or later it will break.
The Cavalry Arms Mark II design is different because the receiver and stock is one large plastic piece for those that are wondering.
