M60 Magazine Holder?

[hmsbrinmaric]

Hi Everyone,

I found this yesterday with a bunch of other stuff. It looks like it hooks onto the feed tray on the M60 and holds a 100 round box of ammo. I have never seen one of these before. Can someone tell me when they were made and if they are common or not? They appear to have been made by Rock Island Arsenal.

Thanks,
Keith
