This is a Bausch & Lomb Balvar 8A 2.5-8x rifle scope. This scope has no internal adjustments; all windage and elevation adjustments are made in the mounts. In this system, the scope is held against the bases by spring tension. This was designed so that the scope could take a hard blow, or be removed, and still return to zero.
This scope is in very good overall condition. There are small marks where the scope contacted the mounts, on the eyepiece adjustment ring, and on the objective lens bell.
The glass is crystal clear with no noted defects and the scope has a tapered crosshair.
