early AR-15/AR-18 large magazine

Attachment 21848Attachment 21847Attachment 21846Attachment 21845One of the first (if not the first) large capacity drum magazines for both the Colt AR-15 and the AR-18 rifles. This one in the photo was sent back on a recall for a modification by the factory. Cartridges are very early: the Rem 222 Special and Winchester 224

Yes, I remember those too. There's one in the hands of an individual I know. I recall it being used 20 odd years ago and it worked OK after some tinkering, but it doesn't get used much now. We don't see them at all now, here...When did you get that one? Do you remember?

Very interesting, good info.
