DESC: Yukon's CS Sharp Shooter Day and Night Vision Riflescope gives you the flexibility and performance you need. This scope easily transforms from a daylight sighting device to a NVRS by simply swapping out the eyepieces. No longer do you need to carry two scopes and lose your zero setting in the process of exchanging them. This day and night scope offers all the features the tactical marksman looks for in a quality sighting device; parallax correction, 1/4 MOA precision adjustments, waterproof housing and recoil proof weapons mounting rail.
