Simple tool to install or remove MX 10169 night vision intensifier tube 4 slot retaining ring, such as those found in a PVS-14.
Not super strong but good enough to cinch the ring down sufficiently. Also helps to get the ring's threads lined up with the threads on the NVG body to avoid cross threading.
Pictures show a 3d printed retaining ring but works on 4-slot aluminum rings, too.
