Description
These are objective lens locking rings required for securing the objective lens assembly to the PVS-14 NVG body housing. Night Vision goggles are expensive, maintain them properly.
The objective-lens lock ring limits the travel of the objective lens so it stops at the point where the monocular reaches infinity focus. Once infinity focus is set, a set screw is installed to prevent the lock ring from rotating. Screw is NOT included.
