The Japanese 6.5 mm Sniper’s Rifle, Model 97, is a manually operated, bolt-action, air-cooled, shoulder weapon similar to the Model 38 (1905) 6.5 mm rifle except for its monopod, turned-down bolt handle, and telescopic sight. The telescopic sight is attached to the left hand side of the receiver by means of a dove-tailed base. It is a fixed focus type of 2.5 power and has a 10° field of vision.
The telescopic sight is approximately seven inches long and is equipped with an eyepiece of soft rubber. The reticle is marked in the following graduations: vertical from 0 to 15, horizontal 20 mils each side of the center, the markings being at 5 mil intervals. The horizontal line intersects the vertical scale at the 3 mark.
The telescopic sight is removable and when not in use is carried in a well constructed canvas case which has a heavy coating of lacquer on the outside for waterproofing. The case is fitted on the inside with a wooden spacer to secure the sight when it is inside. A small pocket to hold the sight cleaning brush is also constructed inside the case.
The rifle is also provided with a folding monopod which is pivoted on the lower band.
