Just curious, I`d like to get some of these lowers, finish and fitum Myself, makeum real fancy too.
Just wondering if anyone has ever tried one of these.
The jig for getting the holes correct is extra.
They are listed as home made or some such so there is no ffl intervention in purchasing or finishing them.
Heck, could even makum Your own brand tooo.

I seen in one site where they are making some from polymars that do`nt require a jug or any sort of special machining tools, only a dremmel tool to make it easier for "Removing only the white".
Just curious is all.

Here is another company, they posted here awhile back;
poly80.com/store/Item/Polymer-Black

They are a tad cheaper and in stock. When they first posted here they were using a 1 time use jig that came with the receiver. Looks like they are doing the same thing with the "cut out the white" idea.

Those look even nicer, good price too.
The reviews I have seen on the polymar units all looks real good, it seems like a fairly inexpensive way to get into an AR15. Just wondering if anyone in the forum has ever messed with one.
My machining skills are nill to none so I do`nt know if I could make Me a new rifle or have an 85 dollar paper weight.
The AR10s does`nrt seem to come in the polymar materials, maybe too much shock for that.
The AR10s in the aluminum are a bit more pricey but they would require some fine machining and I do`nt think the jig would go deep enough so that I would be ensured that everything would fit if I did the grinding with the tools I have, basically a drill press and several die grinders.
To hire out the machine work then purchase the other components would be getting close to the price of purchasing a completed unit, I would think, but I have absolutely no experience in those fields.
I have seen some 95% units too, the more they do the higher the pricing goes.

I've done 80% lowers before. The ones I did were castings and more like 60% as the only thing done was the magwell, so a milling machine, drill press, reamers & oddball tap for the stock was a must. I will point out that someone did do a cheap and dirty AR with the same lower using nothing but hand tools and JB weld. It worked, ugly but functional.

I have the poly80 lower on my wishlist, hopefully before Christmas.

So the Poly AR15 lowers must be a good piece. I was looking for the Poly for the AR10 but could`nt find any so they must not be available, probably to much weight of the moving parts and the poly may not hold up to the shock, just a guess though.

I honestly don't know if the poly80 is any good. There have been successes and failures in the plastic fantastic and I'm hoping this is a success. I'm afflicted with terminal curiosity, so I'm ok with finishing a poly lower just for the sake of butt stroking the ground with it and posting pics of the results. If I had the money to spend, It would be money well spent even if it breaks. I can't help it, I just gotta know and breaking stuff is fun in its own right.
If it does hold up well enough, I see ultra lightweight pack carbine & pistol build following shortly after.

I'd guess the lack of big bore poly lowers is the upper weight. Even the well known Calvary Arms lowers had occasional issues with heavy varmint barrels on AR15's flexing the lower a smidgen.

Does`nt seem Polymar80 has the AR10 lowers available yet.
