This is a replacement plug for the back of your Overlord Marker. It may work on more markers, but that is the only one I tested it on. It is designed to mimic rear iron pistol sights using the spring handle as the front sight. It uses the same o-ring that the original plug used. I printed mine in PETG, but it could be done in different filaments.
