Abstract : The purpose of the report is to establish criteria for the selection of sight design and for the control of sight production. Proposals were made to improve the conventional telescopic sights which employ lenses for the erection of the image. To develop prism erecting sights, because of their inherently superior optical properties and their advantages in ballistic treatment. The development of prism erecting sights has resulted in the M10 (or T8) dual periscopic sight and some progress has been made in the development of a lateral offset sight. It is the purpose of this report to evaluate the progress in improvement of straight tube sights, in terms of criteria which refer particularly to the requirements of the using arm. (Author)
