I first saw 30 round magazines in early 68. One of their problems was they would not fit in the existing pouches. They were in short supply; only one was issued to each man in a line company. I do not remember any particulars as to manufacture or markings.
We (an ordnance maintenance company) received XM177 kits with instructions that they were for the LRRP units, however, officers commandeered most of them. This was probably for the best, as we could not get any of the ones we assemble to function reliably on auto with 20 OR 30 rd. magazines. The colt rep. that gave us a class on assembling these kits to M16s told us that was still a problem. As I understand it, different recoil buffers were developed for the XM177 and that helped, but that was after my time of working on the XM177
