Description: The KVC Obverse Shoe Set (OSS) is intended for applications requiring PVS14 (and various derivative modules) to be paired or oriented for a variety of applications. The OSS maximizes use of virtually any standard BNVD dovetail as a host receiver. The OSS is sold as a set, including a floating top helmet shoe and lower weapon shoe. The top shoe clamps around the PVS14's objective lens locking ring. To install, position the clamp screw so it is accessible with the wrench between the battery cap and gain control knob (we find it easiest to unscrew the battery cap prior to installation). The bottom shoe simply threads into the 1/4-20 insert in the PVS14 body. Each interface can be installed on separate PVS14's, allowing them to pair with the KVC Universal Bridge. They can also be installed on a single PVS14, allowing the monocular to move from the KVC JAMR to the KVC PWM-S for head or weapon mount. OSS shoes will lock into standard female dovetail interfaces from a multitude of helmet mount manufacturers. The helmet mount attachment dovetail shoe features KVCs Tolerance Tooth. This feature is designed to ensure KVC male dovetail will properly seat in any other manufacturers female interface. Due to varying tolerances from one manufacturer to the next, wear, environmental changes, etc; not all dovetails consistently lock up. KVCs Tolerance Tooth allows precise adjustment to compensate for tolerance stack. Even if your Universal Bridge locks up perfectly with the host mount, parts wear will occur from constant mounting reps. Adjusting the Tolerance Tooth will ensure a snug fit throughout the life of the device. OSS Shoes will readily convert your PVS14 for mounting to an KVC Universal Bridge, JAMR, or similar dovetail-based mount. For monocular use, you will need an offset adapter like the KVC JAMR.
