BU-50 - Fits:49.19-50.37mm OD
The Night Optics BU-50 throw-lever clip-on adapter is made from aircraft grade anodized aluminum and mounts directly to the front bell-housing of the day scope.
A specially formulated grip tape is installed on the inner surface of the mount to provide a slip-free interface with the day scope. The tape also protects the finish on the daytime optic.
When selecting the appropriate mount, please use a micrometer (Caliper) to take an outer diameter measurement of the day scope in millimeters. Most of the available mounts offered by Night Optics fit a size range and can be adjusted to fit within that range, however, if a different size is desired, call us directly as custom mounts can be made to order.
