I've seen several variations in "inches" for the M48-M24/47-M24/56C. 4.5 to 4.75 inches is the common answer. Wouldn't the Yugoicon use the metric system to measure these? All my Yugo bolt rifles have a cleaning rod 375mm (14 3/4inch) in length. Is there a variation in the rod length of an 1/4 inch?
