REPORT ON PERISCOPIC SIGHT T8 AND MOUNT T105,

Abstract

Performance of the T8 is superior to any sight previously tested. Sight mount T105 interferes unnecessarily with the armor, thus increasing the time required for installation, but can be used as an interim measure. Head-rest must be modified to incorporate depth adjustability and eliminate interference with helmet. Springs employed in mount to exert pressure on sight are defective in design, necessitating a change to insure proper function and retention in position. Removal of extraneous light in illumination of the 6 power sight reticle is needed for effective night operations. The rheostat does not provide enough range of brightness for reflex reticle. Improvement in eye cup design for 6 power sight is desirable. (Author)
