Mountin, sighting in and zeroing a Viridian RFX15 optic sight
It was easy to mount on my Taurus G3. It was easy to adjust and get sighted in, and it has always been on when I remove the pistol from a holster and present it downrange. It appears to hold its zero at this time, since I only fired fifty rounds. It appears to be of good quality and workmanship, only time will tell.
