The Winchester Model 1866 has earned itself a noted place in American western history. Thousands were carried to the Great Plains and beyond by intrepid American pioneers and were relied upon for defense and hunting. The '66 secured Winchester's place in the annals of the West and launched a long line of successful Winchester lever actions that remain popular to this day and still retain the basic form of the '66.
