Info on 20rd AR-15 Magazines

NOT FOR SALE. I am looking for information on the pictured magazines. I am unable to find any markings on the magazines. I know they are pre-'94, made of steel, and have a clear, tacky residue on them but that is all I know. The magazines came in individual plastic bags and two of them come with a price tag (pictured). Any additional information would be appreciated. I have not disassembled the mags to look for a date stamp. And yes they have been in my constant possession before July 1, 2013. Thanks for any information in advance.

Interesting it says Armalite, yet Armalite 20 rd mags are Al, not steel. I see an EX0068 for 30 rd. There are 10rd steel Armalite mags.

Im voting generic 20 round gun show mags.

I second the notion that they are gun show magazines.

Take this with a grain of salt, my experience is based on pre-94 mags on AR15.com way back when...

Between the fact that these are curved 20-rounders and the green followers, I doubt they are pre-94. From what I understand, the green followers were adopted in the early 90s (as in around the time of the ban). So, I doubt those would have trickled into to new mag market before 1994. All of the USGI pre-94 mags I have came with aluminum followers (which work fine).

It's even more strange that you have one with a black plastic follower that doesn't appear to be "anti-tilt".

Plus if they were Armalite the floorplates would bear the Armalite logo. And they would definitely be aluminum too for 20 rounders

The inconsistencies of the spot welds scream Korean or Chinese knock offs.
