I went ahead and ordered one, I saw where the threaded rod can be replaced if it’s not long enough but supposed to be 1 1/4 long which should be fine. I’ve been messing around with sights lately and made/ modified several , made a couple that had a reference line to allow me to cant the bow the same every shot. I agree that the single pin seems to work as well as anything although I soldered a peice of copper tubing to a sight pin with the dot in the center. Think I’ll be using it only because the tube protects the pin. Going to try the srf to see how I like it.
