Summary  
The document details testing conducted on modified rifle sights and scopes for a 7.62 DOLGUN (VAL) Rifle in June 1964. Donald J. Dunn, TS/D/H, and others tested a modified Williams "Poop" sight and a Japanese-made 2x scope mounted on the rifle. The tests aimed to evaluate accuracy, tolerances, and performance under varying conditions, including reduced and full load ammunition at distances ranging from 25 to 150 yards. Results indicated erratic performance, with inconsistent target hits and issues such as difficulty in zeroing the scope, poor range graduations, and unreliable ammunition behavior. Recommendations included discarding the scope and mount due to unreliability, reducing clicks per revolution on the Williams sight, and further testing to identify causes of instability.
