The BSC-M is the same beam steering mount used on the BSD-2R, Rail Periscope. It incorporates a stainless steel kinematic mount, a steel rail carrier compatible with the X26 optical rails, and a 45-degree mirror holder which is held captive to the kinematic mount so that it will not fall out during manual rotation adjustment. The BSC-M can be used to create custom height versions of the standard BSD-2R, Rail Periscope or it can be used on the X26 rails.


BSC-M与用于BSD-2R轨道潜望镜的波束转向装置相同。它包括一个不锈钢运动支架,一个与X26光学轨道兼容的钢轨载体,以及一个45度镜架,该镜架固定在运动支架上,这样在手动旋转调整时就不会脱落。BSC-M可用于创建标准的BSD-2R、钢轨潜望镜的自定义高度版本,也可用于X26钢轨。
