Abstract: A precision mount has two split rings that directly engage a telescopic sight. The front split ring is mounted on shoulder bolts to provide a pivoting engagement, while the rear split ring is held within a slide and adjusted vertically therein using a precision adjuster. A balanced lock is provided which ensures alignment is preserved during position locking, subsequent to adjustment. Windage is provided on a separate adjustment between the sight yolk and the rifle attachment, thereby isolating windage from position locking and simplifying the appropriate adjustments. Precision connections are maintained at all critical locations, even after shock or recoil, by using precisely dimensioned pins and mating holes in association with standard bolt fasteners.
