This is designed to be used with our metal J-arms and bridge arms. If you want to use it on our polymer arms / bridges, you must shave off the triangular protrusion on the polymer (do not modify this adapter).
Fits ABNV RVM14 and Nocturn Industries Tanto monoculars, and also fits PVS-14 style monoculars that only accept arms / bridges that have a triangular protrusion and not our traditional dual circular contact pads.
Made of aluminum. Made in the USA.
