The Revolver Optic Conversion (R.O.C.) allows for the process of modifying a revolver to accept a red dot sight (RDS). Traditionally, revolvers have been equipped with iron sights, but the trend in recent years is to adapt them to modern sighting systems, such as red dot optics, to improve accuracy, speed of target acquisition, and overall performance.Features :Includes R.O.C.
