80% Old style lowers help

Cant seem to get much info in the general firearms section. Some credible, helpful information related to these 2 lowers I've had for 8+ years would be helpful and appreciated.


OLD STYLE 80% AR LOWERS QUESTION
Are the "old style" AR 80%'ers still ok to sell/trade? I have 2 that I will never be able to do anything with, similar to the Tannery, KT types from around 10 years ago, have had them since then. Similar to these

As well as a "tester" piece/scrap for the buffer hole. These are the need to drill and tap type that came with the fcg area already milled. The newer style have most of the drilling tapping done already. The real question is can I sell/trade these? I have not done anything to them, they are as they came from the mfg way back when. I want to be sure its ok before I offer them up for sale/trade. Appreciate any helpful info.

Well somewhere there is a letter from the ATF saying that these were not at the time firearms. I would reason to guess that they still are not firearms.

But they just may be as the ATF has been know to change their minds.
And your links are dead

You should be fine selling them. Drilling out and tapping that hole IMO is FAR more difficult than milling the FCG pocket. And some of the side holes are pretty tricky to drill as well.

To do the buffer hole operation right, you need a large solid floor drill press with a vise mounted to the table IMO. Nothing else will do it quite properly (maybe a big lathe?).

10 years ago this was the only option to legally home build without a end mill. My aspirations surpassed my ability unfortunately.
