Factory Colt 9MM SMG And Sub-Carbines

RO633-experimental1
It is easy to forget that the Colt once experimented with many variations of the AR-15 platform. Over the years they made many attempts to develop what we would call today a PDW. TFB writer Ethan hascataloged every 9mm Colt SMG-style sub-carbine they developed over the years on his personal gun blog. He dug up a number that I had never seen before. I highly recommend checking them out.
