New here and already asking for favors, I know I know. I'm that guy. Was wondering if anyone could identify this part for me. I found it in my Automag collection boxes and thought I'd ask here first. It has a small dovetail on one side and a threaded hole and a threaded post on the other. Only measures 2" x 1.5". If not AGD related, then any point in the right direction would be much appreciated. Thanks in advance.
