In the 1960's, I aquired one of the first Universal carbines. I fired thousands of rounds of GI, factory, and reloads through it. It was accurate and never once malfunctioned in any way. In the mid 1990's, I shot a late Universal. It looked crude, and when I shot it the primers nearly blew out of the pockets of GI ammo. It is possible to get a good Universal carbine, but I suspect most out there now are more like the quality of the latter carbine.
