This telescopic rifle sight is built with all the authenticity that has made the standard length "Wm. Malcolm" scope such a restounding success among shooters needing a "period correct" circa 1870-1880 precision sighting system - only in a new shorter, more compact length. Measuring 17" overall, this 3X telescopic sight is perfect for mounting on shorter barrels, especially on the 22 to 26" barreled lever-action rifles. Built with a strong 3/4" diameter steel tube, adjustable focus eye-peice, fully multi - coated lenses, long 4" eye relief and windage/elevation adjustment external mounts.
