The Sightmark PVS-14 Slide to Side Mount is designed to be mounted to the PVS-14 night vision monocular and provide the shooter with versatility of adapting to light and dark shooting environments. When the shooter does not need the PVS-14 to engage targets in lit environments, the slide-to-side mount is pushed to the side and down. This removes the PVS-14 from view of the optical weapon sight, but still makes it easily accessible when needed. The Slide to Side mount attaches onto the PVS-14 objective lens lock ring, allowing the objective lens to rotate freely for focusing. Sightmark PVS-14 STS QD Mount SM34001
