Recently, I came across the Wikipedia article for 'Operation Red Dog' which was the codename for a plan by white supremacists to overthrow the governments of the Barbados and Dominica in 1981. The plotters ended up being arrested by federal agents, who seized a large quantity of weapons, including some semi-automatic rifles that I am wondering if anyone can identify. They appear to be civilian models of a military design, but I've never seen anything that resembled them before.
