Thinking about an Amega scout mount for my M1. It won't destroy the historical value as it only removes the front handguard. The purpose is to increase speed of target acquisition and accuracy, esp in low light. My questions are as follows. What type of sight might cowitness or at least come off easily in an emergency so irons can be used as a backup? Would a 1X or a magnified optic better fulfill my requirements? What are the drawbacks to this idea?
