AB Night Vision RNVG Dovetail Riser Extension

The new RNVG spacer improves upon the RNVG and moves the dovetail mounting point approximately 0.80” up and 0.80” forward, positioning it better to allow fewer users to have to max out their mount adjustments or fiddle with their helmets as much for proper positioning. Installation is very simple: To assemble the RNVG Dovetail Extension, you will remove the dovetail screws on your RNVG, screw down the RNVG Dovetail Extension taking care to ensure that the battery cap retention lanyard is captured under the Dovetail Extension, and then screw your dovetail to the RNVG Dovetail Extension.  Four screws (the four original mounting screws are re-used for installation) and a 3/32″ Allen wrench are included in the package. Like many fixed bridge goggle systems, the RNVG is based on the basic layout and architecture of the AN/AVS-6/9 ANVIS systems, however the mounting interface of ANVIS systems is much different than the more common and well known BNVS or “dovetail” mounting configuration s
