No FFL 80% Polymer Lowers

[fightingquaker13]

Peg, here's the consensus. You MIGHT have a loophole if the thing doesn't have a serial number, if it does its a firearm. But once assembled it needs to go through the system. Just order it through an FFL. Its not worth the risk. Seriously, you're looking at 5-10 years if you freak around here. Just do it  right buddy.

I have a polymer lower on a 9mm AR. No issues at all. I really like it. But I don't thing I would care for it on anything more than a 9.

The advantage I see to something like this is that it's similar to a Liberator from WWII. You have a firearm no one knows about that can be used in a emergency situation and possibly to get you a better weapon. Ideally, it never has to have a full magazine run through it.

This isn't the lower receiver that you use to build your primary rifle. This is for one of two things. 1. Use it to build the cheapest rifle you can that shoots. It can be used and tossed with little regret if need be. 2. Use it to build a cheap, disposable, lower, or possibly, put quality of you want spare parts or to swap them later. Put the upper that is exactly what you want to your specs on it. Use it to "acquire" a better lower and put the upper on it. You basically have the rifle you want and some spare parts.

Palmetto State Armory has been running intermittent sales on their blems as well.

Yes it is legal.  If the lower is not completed to a sufficient degree it is not considered a firearm.  (kind of like a block of steel is not a firearm).  Some of the companies selling these will offer a letter showing the ATF determination verifying it's legality. 

You do not need to serialize them if you do not wish to.  You can sell them  - however you cannot manufacture with the intent to sell without the license required.

I wouldn't want a lower with "forging defects", especially since they can't be returned. Any other cosmetic blemishes would be okay.

Thanks for the link.... these are good prices for uppers and lowers........ good to keep in mind for building a rifle.

I agree, and have to admit that I missed the forging defects part on the page. I would say it is misleading when the page title says "cosmetic blems". Perhaps the forging defects are in appearances such as surface fluid runs? it has been my experience with the PSA blems that there is almost no discernable difference between them and non-blem. YMMV

[PegLeg45]

They have good prices on the non-blems also.

The tooling need to complete one of these is pretty extensive.  I have a tool collection that make most men get a hard on,  i have a bridgeport and a lathe, but it would still be a could hundred bucks in tooling( or making lots of fixtures/jigs) to complete one of these.   i supose you could do it with a kick ass drill press and a bunch of hand files, but most people can't even square the table on thier drill press let alone locate holes correctly.   its not as easy as you think.
